Answer 1

Answer:

Plz mark my answer to brainliest

Step-by-step explanation:

The exterior angle theorem asserts that if a triangle's side gets extended, then the resultant exterior angle will be equal to the total of the two opposite interior angles of the triangle. According to the Exterior Angle Theorem, the sum of measures of ∠ABC and ∠CAB will be equal to the exterior angle ∠ACD.

Answer 2

Answer:

The exterior angle theorem asserts that if a triangle's side gets extended, then the resultant exterior angle will be equal to the total of the two opposite interior angles of the triangle. According to the Exterior Angle Theorem, the sum of measures of ∠ABC and ∠CAB will be equal to the exterior angle ∠ACD.
