# Finding the missing angle of a triangle worksheet

For instance, if you are given an angle of 90° that has been split into two smaller angles, you can use subtraction and addition skills to solve the problem.
The vertices are already labelled with A located on the angle we are using so we only need to label the opposite sides of a, b, and c.

The other two angles are represented by an algebraic.
