Select all the true statements.

• ∠3 ≅ ∠2 because they are alternate interior angles.

• m∠1 + m∠3 = 180 because they form a straight angle.

• ∠3 ≅ ∠6 because they are alternate interior angles.

• ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180.

• ∠1 ≅ ∠3 because they are vertical angles.

What is m∠2 + m∠3? Explain.

• 180; m∠1 + 90 = 180, so m∠2 + m∠3 = 180.

• 180; m∠1 + 90 = m∠2 + m∠3, so m∠2 + m∠3 = 180.

• 90; m∠1 + m∠2 + m∠3 = 180. m∠1 = 90, so m∠2 + m∠3 = 90.

• 90; ∠2 and ∠3 are corresponding angles, so m∠2 + m∠3 = 90.

If m∠4 = 35, find m∠2. Explain.

• 55; ∠2 and ∠4 are complementary angles, so m∠2 = 90 − m∠4.

• 35; ∠2 and ∠4 are corresponding angles, so m∠2 = m∠4.

• 145; ∠2 and ∠4 are supplementary angles, so m∠2 = 180 − m∠4.

• 35; ∠2 and ∠4 are alternate interior angles, so m∠2 = m∠4.
