How to find the angle of a triangle?

To find the angle of a triangle:

  1. Subtract the two known angles from 180°.
  2. Plug the two angles into the formula and use algebra: a + b + c = 180°

Given,

E + D + F = 180

52 + D + F = 180

D + F = 180 - 52

D + F = 128°

A triangle is a three-sided polygon that consists of three edges and three vertices.
