Question

1. problem solving the painted lines that separate parking spaces are parallel. the measure of ∠1 is 60°. what is the measure of ∠2? explain.
2. open - ended describe two real - life situations that use parallel lines.

Explanation:

12.

Step1: Identify angle - relationship

Since the lines separating parking spaces are parallel, ∠1 and ∠2 are corresponding angles. Corresponding angles formed by parallel lines and a transversal are congruent.

Step2: Determine measure of ∠2

Given that m∠1 = 60°, and ∠1≅∠2, then m∠2 = 60°.

Railroad tracks are parallel as they run side - by - side without intersecting to allow the train wheels to run smoothly. Also, the lines on a ruled notebook paper are parallel, providing a consistent guide for writing straight lines of text.

Answer:

The measure of ∠2 is 60°.
