Would you use SSS or SAS to prove the triangles congruent?

SAS; three pairs of corresponding sides are congruent.

SAS; two pairs of corresponding sides and their included angles are congruent.

SSS; two pairs of corresponding sides and their included angles are congruent.

SSS; three pairs of corresponding sides are congruent.

Does the transformation appear to be a rigid motion? Explain.

No, the two figures appear to be similar but not congruent so the transformation must not be a rigid motion.

Yes, the two figures are titled image and preimage so the transformation must be a rigid motion.

Yes, the two figures appear to be congruent so the transformation seems to be a rigid motion.

Yes, the the image is a reflection of the pre-image and a reflection is a rigid motion.

△BIG has vertices B(-4, 2), I(0, -3), and G(1, 0).
Graph △BIG and its reflection, △B'I'G', across the y-axis.
Then graph △B"I"G", after a translating △B'I'G' (x + 3, y - 1).
Finally, rotate △B"I"G" ninety degrees clockwise around the origin to graph △B'"I'"G'".
Label all vertices.
