Question

For lines c, d and e, m∠1 = 90° and m∠3=90°

For the given diagram and angle measures, use complete sentences to describe each pair of lines as parallel or perpendicular. In your description, include the special angle relationship between angles 1 and 3.

a. lines d and e
b. lines d and c

Answer 1

a) lines d and e are parallel lines

b) lines d and c are perpendicular lines

angle 1 and 3 are corresponding angles and they are equal. As c and d are perpendicular lines m∠1 = m∠3 = 90

Explanation:

Answer 2

Explanation:

a) lines d and e are parallel lines

b) lines d and c are perpendicular lines

angle 1 and 3 are corresponding angles and they are equal. As c and d are perpendicular lines m∠1 = m∠3 = 90
