Question

what are the theorems associated with triangles, and how can they be used to find missing angle measures?

Answer 1

Answer:

We use Pythagorus Theorem for Right-Angled Triangles and theorems like

S-S-S (Side-Side-Side), S-A-S(Side-Angle-Side), A-S-A(Angle-Side-Angle),

A-A-A(Angle-Angle-Angle), R-H-S(RightAngle-Hypotenuse-Side).

To find out 1 side of triangle, We use = 180° - (Sum of 2 sides)
