Question

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°

Answer 1

Answer:

The measure of angle A' is 125°

Step-by-step explanation:

we know that

Under reflection, lengths, areas and angles do not change but orientation does

therefore

If angle A is 125°

then

after the reflection

m∠A=m∠A'

therefore

The measure of angle A' is 125°
