Question

question 13 (multiple choice worth 1 points) id: 6087 mc eric reflected parallelogram abcd across the x - axis. if angle a is 125° and angle b is 55°, what is the degree measurement of angle a? 55° 180° 70° 125°

Explanation:

Step1: Recall reflection property

Reflection across an axis is a rigid - motion transformation. Rigid - motion transformations preserve angle measures.

Step2: Determine angle measure of A'

Since angle A in parallelogram ABCD is 125°, and reflection preserves angle measures, angle A' will have the same measure as angle A.

Answer:

125°
