1) In the figure below, m_2 = 60°. Find the measure of each angle. Write which postulate(s) or
1 answer:
Answer:
Step-by-step explanation:
From the picture attached,
Two lines are the parallel lines and a third line (transversal line) is intersecting these parallel lines.
m∠2 = 60°
a). m∠1 + m∠2 = 180°
m∠1 + 60° = 180°
m∠1 = 180° - 60°
m∠1 = 120°
b). m∠2 = 60° [Given]
c). m∠2 = m∠8 = 60° [Alternate exterior angles are equal]
