. Name the congruent parts.

AB and CD

<A = <C

This is given information, but everything on this might or might not be congruent, since it has the same angles and side lengths.

It might be symmetrical along E and vertically downwards, but no garuantees since the image is a bit warped.

Step-by-step explanation:

A simple thing to remember is that the notches in the angle symbols and the sides mean that they are congruent. If a side has 2 notches, every other side that has 2 notches are congruent.

Angles and sides are not congruent of course, but angles that have the same number of notches are equivalent.

So with this in mind, we know stuff.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
