A. m∠4 = m∠1 + m∠2

C. m∠4 = 180° − m∠3

  • In any triangle ABC the measure of the exterior angle is equal to the sum of the interior angle opposite to it.
  • The sum of exterior angle and interior angle is equal to 180 degrees.

So we can write

m∠4 = m∠1 + m∠2

And m∠4 + m∠3= 180°

m∠4 = 180° − m∠3

Therefore, the correct equations are :

A. m∠4 = m∠1 + m∠2

C. m∠4 = 180° − m∠3
