The word Geometry is derived from the two ancient Greek words, “Geo” and “Metron” where Geo stands for Earth and Metron stands for measurements.
Geometry is the branch of mathematics that deals with shapes (Circle, triangle, rectangle, oval, square, etc.), angles, dimensions, and sizes of a variety of things that we experience in our daily life. This branch of mathematics lets us learn about different angles, transformations, and similarities in the figures. Some of the examples of topics of geometry are explained below:

Implementation: Calculate the circumference of a circle with an 8 cm radius. C = 2πr , C = 2(3.14) (8) Thus C = 2 (25.12) C = 50.24 cm
3. Perimeter and Area of Equilateral Triangles
A type of triangle whose all three sides are equal, as well as all the three angles, is equal to 60° each is known as an Equilateral Triangle. To calculate the perimeter of an equilateral triangle the sum of its three sides is calculated hence the formula is, P = 3a , Where, P = Perimeter , a = one side of the triangle. Since an equilateral triangle has equal sides the sum is represented as 3a
Implementation: Find the perimeter of an equilateral triangle with a side of 9 units. P = 3a, a = 9, P = 3 (9), thus P= 27 units.
4. The Area of Circles with Diameter Values.
