What is the measure of angle C?

60 degree

Step-by-step explanation:

When congruent sides for the whole triangle are shown we know they have equal angles also, so we call them equilateral triangle.

We try 60, 60, 60 and they all add up to 180 degree,

so we know angle C = 60 deg

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
