Question

Use the diagram for Exercises 5-8.

Answer 1

Answer:

Step-by-step explanation:

5). ∠2 ≅ ∠6

   By corresponding angles theorem both the angles will be congruent.

6). m∠3 + m∠5 = 180°

  If two lines are parallel and a transverse cut these parallel lines, pair of consecutive angles in one side of the transverse are supplementary.

  [Consecutive interior angles theorem]  

7). Given : m∠1 = 71°

  Therefore, m∠1 = m∠5 = 71°  

   By corresponding angles theorem ∠1 and ∠5 are corresponding   angles.
