At the beginning of the week, a particular stock sold for 29 3/8 per share. At the end of the same week it solf for 31 2/8. What was the amount of increase per share?

the answer is c.) yes, [triangle]klp can be reflected across the line containing [line]kp and then translated so that p is mapped to m.

the reason is this:

looking at the triangles visually we can see they share the same features. using rigid transfromations we can reflect it over [line]kp then all we need to do is translate up.
