Question

the angle is to be reflected over the line shown. what would be the measure of the reflected angle?
a it would have the same measure as the original angle
b it would have half the measure of the original angle
c it would have double the measure of the original angle
d there is not enough information to know the measure of the reflected angle

Explanation:

Step1: Recall the property of reflection

Reflection is a rigid transformation. Rigid transformations (such as reflection, translation, rotation) preserve the shape and size of the figure.

Step2: Apply the property to the angle

Since an angle is a part of a geometric figure, when an angle is reflected over a line (a rigid transformation), the measure of the angle does not change.

Answer:

A. It would have the same measure as the original angle
