Geometry-Geometry Formulas


Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things.

Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes. These shapes have only 2 dimensions, the length and the width.Solid objects are also known as 3D objects having the third dimension of height or depth.

Angles in Geometry:

In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. An angle is represented by the symbol ∠.

Types of Angle:

    • Acute Angle

An Acute angle (or Sharp angle) is an angle smaller than a right angle ie. it can range between 0 – 90 degrees.

    • Obtuse Angle

An Obtuse angle is more than 90 degrees but is less than 180 degrees.

    • Right Angle

An angle of 90 degrees.

    • Straight Angle

An angle of 180 degrees is a straight angle, i.e. the angle formed by a straight line
