Question

This diagram shows an equilateral triangle and three lines, p, q, and r, that meet at the

triangle's center, T.
Select all of the transformations that map the triangle onto itself.
reflection across line q followed by 90° clockwise rotation about point T
reflection across line p followed by 240 clockwise rotation about point T
reflection across liner
270 clockwise rotation about point T
120 counterclockwise rotation about point 7
180 counterclockwise rotation about point 7 followed by reflection across
sine q

Answer 1

Answer:
-Reflection across line p followed by 240 clockwise rotation about point T.

-Reflection across line r.

-120 counterclockwise rotation about point T.

Explanation:

All these transformations map the triangle onto itself.
