Question

For the angles shown in the diagram, which statements are true? Select all that apply.

A.The sum of m∠3 and m∠4 is 180°.

B.The sum of the measures of the adjacent interior angle and one of the remote interior angles is equal to the measure of the exterior angle.

C.∠3 is supplementary to ∠1.

D.m∠4 = m∠1 + m∠2.

E.m∠1 + m∠2 + m∠3 = 180

Answer 1

Answer:

A, D, E

Answer 2

The statements that are true include:

• A.The sum of m∠3 and m∠4 is 180°.
• D.m∠4 = m∠1 + m∠2.

• E. m∠1 + m∠2 + m∠3 = 180°

It should be noted that the sum of angles that are in a triangle equals 180°. Therefore, m∠1 + m∠2 + m∠3 = 180°.

Also, the sum of m∠3 and m∠4 is 180°. This is because the angle on a straight line equals 180°.
