Line segment CD is shown on a coordinate grid:

A coordinate plane is shown. Line segment CD has endpoints 1 comma 2 and 1 comma negative 1.
The line segment is reflected about the y-axis to form C′D′. Which statement describes C′D′? (4 points)


C′D′ is perpendicular to CD.

C′D′ is half the length of CD.

C′D′ is greater than twice the length of CD.

C′D′ and CD are equal in length.

The reflection of Triangle ABC would have vertices at 3, 0, 3, 3, and 1, 3.

Therefore, the option "A coordinate plane is shown. A triangle has vertices 3, 0, 1, 0, and 3, 3" is the reflection of the shape.

Based on the given information, the rotation described is a counterclockwise 90-degree rotation.
Answered by GPT 3.5
If angle X is rotated 60 degrees, the measure of angle X′ will be 110 degrees + 60 degrees = 170 degrees.

Therefore, the correct answer is 170 degrees.
