Performance Task: Congruency Proofs
Question 2 of 15 • MS-Geometry
On a coordinate plane, 2 triangles are shown. Triangle A B C has points (negative 1, negative 1), (2, negative 1), and (negative 1, negative 5). Triangle R S T has points (1, 1), (1, 5), and (4, 1).
Answer
A
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left.B
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the y-axis and a translation 2 units down.C
The figures are not congruent. Point R corresponds to point A, but S corresponds to B and T corresponds to C.D
The figures are not congruent. Point R does not correspond with point A.
