Question

The triangles are congruent by SSS or HL. Which transformation(s) can map PQR onto STU? translation only rotation only rotation, then reflection reflection, then translation​

Answer 1

Answer:

D

Step-by-step explanation:

Consider reflecting first and then translating.

Answer 2

The transformation that can map ΔPQR onto ΔSTU is;

Option D; reflection, then translation.

From the triangles given, we want to map ΔPQR onto ΔSTU.

• We can see that ΔPQR is in a position that is more or less a mirror copy of ΔSTU. Now, when an object is mirrored it means it has undergone reflection which is like flipping an object over a line and not changing the size or shape.

• After reflection again of ΔPQR, since we want to map it to ΔSTU, we must make it undergo translation so that it can be fully mapped unto ΔSTU.

• In conclusion, the transformation that can map ΔPQR onto ΔSTU is reflection, then translation.
