Finish the following proof. Given angle 4 = angle 5 Prove m angle 2 + m angle 3 = 90 degree Given: a || b, a c, and b d

Solution:

29. Reason 2.Since adjacent angle on line are equal

( Explantion : On any line m< 5 +m <4 = 180 and thne m <4+ m<4= 180 and hence m<4 = 90 = m<5)

30. Statement: 3. m<5 = m<2 + m<3

Reason 3: vertically opposite angles are equal

31. Reason 4 : Since m<5 = 90 and m<2 + m<3 = <5 therefore m<2 + m<3 = 90
