Peter reflected trapezoid ABCD across the y-axis. If angle A is 115° and angle B is 65°, what is the degree measurement of angle A′?

Respuesta :

Answer: 115

Step-by-step explanation:

Reflections are rigid motions, meaning angles A and A' are congruent.

the degree measurement of angle A is 115 degrees

Transformation

Transformation is the movement of the point from its initial location to the new location.

Types of transformation are reflection, or rotation, or translation and dilation.

Peter reflecting the trapezoid ABCD across the y-axis wouldn't change the degree measurement of angle A

The degree measure of a angle A is 115 degrees

How to determine the degree measurement of angle A?

by the question, we have:

A = 115 degrees

B = 65 degrees

The transformation is the reflection across the y-axis

Reflection is the rigid transformation, or it does not change the angle measure or side lengths.

After the transformation; we have:

A = 115 degrees

B = 65 degrees

Hence, the degree measurement of angle A is 115 degrees
