Question

3.2 extra practice
in exercises 1 and 2, find m∠1 and m∠2.
1.

Explanation:

Step1: Identify angle - relationship for ∠1

∠1 and the 41° angle are corresponding angles. Corresponding angles are equal when two parallel lines are cut by a transversal.
$m\angle1 = 41^{\circ}$

Step2: Identify angle - relationship for ∠2

∠2 and the 41° angle are vertical angles. Vertical angles are equal.
$m\angle2 = 41^{\circ}$

Answer:

$m\angle1 = 41^{\circ}, m\angle2 = 41^{\circ}$
