Triangle ABC is graphed in Quadrant I of a coordinate plane, and none of the vertices have an x-coordinate or
y-coordinate of 0. Triangle ABC is rotated 90° clockwise with the origin as the center of rotation to create triangle
A'B'C'.
Which statement must be true?
А)
The sum of the angle measures of triangle A'B'C' is 90° more than the sum of the angle measures of
triangle ABC
B The side lengths of triangle A'B'C' are greater than their corresponding side lengths of triangle ABC.
Each angle measure of triangle ABC is less than the corresponding angle measure of triangle A'B'C'.
D. The corresponding sides of triangle ABC and triangle A'B'C' are congruent.
