Question

Geometry, Please help!

Answer 1

Melissa drew two triangles; triangle ABC and triangle PQR, on a coordinate grid. The coordinates of the vertices of triangle PQR are P(3, 3), Q(3, -1), and R(9, -1). The coordinates of the vertices of triangle ABC are A(2, 9), B(2, 5), C(8, 5).

Which postulate can be used to prove that the two triangles are congruent?

Answer 2

a. SSA
b. SAS
c. SSS
d. AAA

Answer 3

Hint: Plot the points on a graph grid.

Answer 4

Plot the points on a graph and then find the distance between the points. You will prove that the two triangles are congruent, since all their sides are equal by SSS.
