In contrast to other attributes such as colour, texture, or material type, a form or figure is a graphical depiction of an object or its external border, outline, or external surface. In contrast to solid 3D shapes, a plane shape, two-dimensional shape, or 2D shape is limited to lie on a plane. Everything we observe in our surroundings has a shape. In the items we see around us, we can find different basic forms such as the two-dimensional square, rectangle, and oval or the three-dimensional rectangular prism, cylinder, and sphere. Credit cards, bills and coins, finger rings, photo frames, dart boards, cottages, windows, magician's wands, tall structures, flower pots, toy railways, and balloons are all examples of geometric shapes.

The colour, overall size, and orientation of a two-dimensional or three-dimensional shape are referred to as non-defining qualities because they do not define or alter the shape in any manner. These characteristics can alter without affecting the form. Determining properties such as the number of sides (parallel or non-parallel, straight or curved), vertices, edges, and faces of a shape, whether the shape is open or closed, and angle measures, on the other hand, determine the shape of a two-dimensional or three-dimensional item. Any change in these distinguishing characteristics will cause the form to shift.

The shape of an object can be defined as its boundaries or outline. It is the surface that we see, and it is independent of the size or colour of the item. Every object in our environment has a unique shape, such as a square, rectangle, or three-dimensional sphere. Have you seen the globe, a replica of the Earth? What is the size and form of this globe? Have you ever noticed how a pizza is shaped? It has a circular form. When we cut a slice of pizza, it takes on a triangle shape. Let us learn everything there is to know about shapes, sorts of shapes, and geometric shapes.

Shapes constitute an object's boundaries and can be distinguished in a variety of ways based on their attributes. These shapes are connected by a boundary formed by merging curves, points, and line segments. Depending on the structure, each form has a name. A few examples of shapes are circles, squares, rectangles, triangles, and so on.

A number is a mathematical object that can be used to count, measure, and name things. The natural numbers 1, 2, 3, 4, and so on are the original examples. Number words can be used to represent numbers in language. Even and odd numbers, prime and composite numbers, decimals, fractions, rational and irrational numbers, natural numbers, integers, real numbers, rational and irrational numbers, and whole numbers are all possible in mathematics. What is the definition of a number? A number can be defined as a count, as in a race, when we say, "3, 2, 1, GO!" or as a measurement, as in John Cena weights 275 lbs. There are also fractions like 22/7 and decimals like 3.14. Numbers are an essential aspect of our daily life, from the number of hours we sleep at night to the number of laps we take around the track. Numbers define world records, sales, and mileage - you name it, and it has a number associated with it.

Numbers are categorised in a variety of ways. A cardinal number is any natural number, such as 1, 2, 3, and so on. We utilise cardinal numbers to count. An ordinal number is a numerical pattern that is similar to a pattern for numbers. It is a number that represents an object's location. For example, first, second, third, and so on. Ordinal numbers are commonly used for ranking. As previously said, numbers are categorised into numerous categories. Let's take a look at some of the most common and essential forms of numbers that we encounter.

Color is a visual perception quality resulting from the interaction of the spectrum of light with the photoreceptor cells of the eyes. All of the hues of the rainbow are mingled together in the sun's rays. This composition is referred to as white light. When white light reaches a white crayon or marker barrel, we see it as white because it absorbs no colour and reflects all colours equally. A black crayon or marker cap absorbs all colours evenly and reflects none, giving it the appearance of being black to us. Scientists do not consider black to be a colour because it is the absence of all colour.

Color is present in all light beams. Electromagnetic waves make up light. These waves radiate from any source of light, such as the sun. Light waves travel at breakneck speeds (186,000 miles or 300,000 kilometres per second). Varied colours have different wavelengths, which are the distances between the corresponding sections of two waves. Red has the longest wavelength of light that humans can see. Violet is the shortest. Although ultraviolet has a shorter wavelength than visible light, humans cannot detect it. Ultraviolet light can be seen by some birds and bees. Infrared light has a longer wavelength than red light, and while humans cannot see it, they can feel the heat it produces.

Color is defined as the appearance of things caused by the different quality of light reflected or emitted by them. Light is required to see colour. When light strikes on an object, some colours reflect off of it while others are absorbed by it. Our eyes can only see colours that have been bounced off or reflected. Sir Isaac Newton was the first to uncover the relationship between colour and light. As Newton found, sunlight is made up of seven main hues that may be seen through a prism: red, orange, yellow, green, blue, indigo, and violet. This composition is referred to as white light. When we see white light strike a white item, we see it as white because it absorbs no colour and reflects all colour evenly. This colour light is reflected back when it touches a coloured item. A black object absorbs all hues equally and reflects none, giving it the appearance of being black to us. Scientists do not consider black to be a colour, but artists do since black is the absence of all colour.

Subtractive hues, on the other hand, are produced by entirely or partially absorbing (also known as subtracting) some light wavelengths while reflecting others. White is the starting point for subtractive colours. When you add filters to white light, such as ink, it takes on the illusion of colour. The CMYK colour system is an example of subtractive colour use, since images, magazines, and other printed materials employ subtractive colour to reflect and absorb light so that we can see.

The best light for viewing colour is diffuse daylight, which occurs when the sun is mostly hidden behind clouds and it is mildly raining. This creates the most accurate colours. It is more difficult to see colour precisely in artificial light. The fundamental explanation for this is because artificial light, such as that emitted by a fluorescent lamp, is frequently coloured blue or red.

As a result, a hue can seem differently depending on the light source. Because the light source lacks adequate blue, even natural light, such as candlelight, emits a surplus of yellow and red. Metamerism is the phenomena in which colours appear to be the same in one light but are different in another.
