The area of a 2D shape is a measure of the amount of space inside the shape.

It is typically measured in square units (such as square meters, square centimeters, etc.).

The shapes known as two-dimensional (2D) shapes, or flat shapes, have only two dimensions.

The area of shapes such as circles, triangles, squares, rectangles, parallelograms, etc., represents the region they occupy in space.

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

A shape that takes up an area of three square meters would have the same total area as three squares with the same size.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

Since different three-dimensional objects have different shapes, their volumes are also variable. Let us look at some three-dimensional shapes and learn how to calculate their volume(V).

An angle is a geometric figure formed by two rays, called the sides of the angle, sharing a common endpoint, known as the vertex of the angle.

Angles are measured in degrees or radians, which quantify the amount of rotation from one ray to the other around their common vertex.

The size of an angle is typically measured in degrees (°) or radians (rad). One complete revolution is 360 degrees or 2π radians.
