Triangle ABC is reflected over the line y = -x. What are the coordinates of B'?
A (3, -1)
B (5, -2)
C (4, 2)
B' (2, -5)
400
LMN is congruent to BCD. If the measure of angle L is (5n + 34) degrees and the measure of angle B is (14n - 2) degrees, what is the measure of angle B?
54 degrees
400
Does Mrs. Galletti have a pet?
NO
500
"a quantity that has both direction and magnitude"
a vector
500
What transformation replicates two reflections in the same direction?
Translation
500
In triangle ABC, angle A measures 55 degrees, and angle B measures 50 degrees. In triangle XYZ, angle Y measures 50 degrees and angle Z measures 75 degrees. Is it possible for the triangles to be congruent? Explain.
Yes! Angle C measures 180 - 50 - 55 = 75 degrees, and angle X measures 180 - 50 - 75 = 55 degrees. Angles A, B, and C correspond with angles X, Y, and Z, respectively, and corresponding angles are equal in measure.
