Given that the two triangles shown are congruent, explain one way to verify that the corresponding angles of the two triangles are congruent. a) reflect triangle 1 across the y-axis b) reflect triangle 2 across the y-axis c) rotate triangle 2 counter-clockwise 90° about the origin d) reflect triangle 2 across the y axis and rotate 90° about the origin at

The correct option is C.

Step-by-step explanation:

From the given graph it is noticed that the vertices of triangle 1 are P'(-2,2), Q'(-4,4) and R'(-2,4). The vertices of triangle 2 are P(2,2), Q(4,4) and R(4,2).

If a figure rotated counter-clockwise 90° about the origin, then

If we rotate triangle 2 counter-clockwise 90° about the origin, then[

If we rotate triangle 2 counterclockwise, then we get the triangle 1.

Therefore the correct option is C.
