Points A B, and Cform a triangle. Complete the statements to prove that the sum of the interior angles of AABC is 180°.

Statement

Reason

Points A, B, and form a triangle.

given

Let DE be a line passing through Band parallel to AC. definition of parallel lines

23 25 and 2124

m_1 = m24 and 23= m25

m24+ m2 2 + 25 = 180°

angle addition and definition of a straight line

substitution

m21 + m2 2 + m23 = 180°
