Javier wants to prove that the base angles of an isosceles triangle are congruent. To do this, he draws triangle with AB = BC. He will then prove that and are congruent by dividing triangle into two triangles and using triangle congruence.

78.59 is the mean

step-by-step explanation:

which expression represents the approximate length of bc?

step-by-step explanation:

yes

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.
