Question

these two triangles can be shown to be congruent using which transformation?

A) reflection over the x-axis
B) reflection over the y-axis
C) translation right 4 units
D) rotation of 180 degrees

Answer 1

Answer:

This is B) A reflection over the y-axis.

Step-by-step explanation:

You can tell this in a picture due to the fact that each point on the corresponding triangle is equidistant from the y-axis. Take the point at the bottom for instance. In both pictures, it is 2 spaces away from the y axis.
