Triangle Sum Theorem

Step-by-step explanation:

Statement

2. m∠H + m∠J + m∠K = 180°

Reason

Triangle Sum Theorem

Comments

-----------

In any given triangle the sum of its interior angles must be equal to 180º.

This has to do with lines and parallelism, and if you trace a Triangle and to parallel lines one of them being the base of it, this can be proven too.
