Geometry

Before we move further, let's look at what geometry is all about

Geometry Definition

Geometry is the study of different types of shapes, figures and sizes in Maths or in real life. The study of different types of shapes has to do with the area, perimeter, volume, surface area, etc of the shapes.

Under geometry, we have essential and commonly used mathematical formulas. Below are the list of them.

Formulas For Area

Rectangle ==> length × width

Triangle ==> 1/2(base × height)

Circle ==> 𝛑r^2, where r is the radius.

Trapezoid ==> 1/2(a + b)×height, where a and b are the bases.

Formulas For Perimeter

Rectangle ==> 2×(length + width)

Square ==> 4l , where l is the length

Triangle ==> (a + b + c), where (a, b, c) are the three sides

Circumference of a Circle ==> 2𝛑r

Formulas For Volume

Cube ==> l^3, where l is the side length.

Rectangular Prism ==> length × width × height

Sphere ==> 4/3𝛑r^3

Cone ==> 1/3𝛑r^2×h

Formulas For Surface Area

Cube ==> 6s^2

Cylinder ==> 2𝛑r(r+h)

Sphere ==> 4𝛑r^2

Pythagorean Theorem

For a right triangle ==> a^2 + b^2 = c^2, where c is the hypotenuse.
