Angles are one of the key essential requirements in geometry. How do you define a rectangle from a rhombus? Both have 4 sides, both have two pairs of parallel lines (they are both parallelograms). The answer? Angles. The rectangle has 4 90 degree angles, while the rhombus doesn't have any 90 degree angles. (In fact, a 90 degree angle is called a "right angle.")
And in more complicated mathematics, you can use angles to calculate angular velocities (which helps you calculate rpms).
Angles like numbers are everywhere. If you ever do anything with carpentry or woodworking (or most craft projects), you will need an understanding of angles.

How do you solve an angles?
Using a protractor is the simplest way of solving the measurements of angles.
What are negative quadrant angles?
using protactor, we use to draw angles in anticlockwise direction and that angles are called positive quadrant angles. and angles in clockwise direction, these angles are called negative quadrant angles.
How are angles calculated?
by using a protractor
How do you find angles in a triangle using only the lengths?
By using trigonometry
Can we draw all angles without using protracter?
No.
