5. The art club designed the logo shown. What transformations did they use if the top trapezoid is the pre-image and the bottom trapezoid is the image?

6. Charlotte use the stem to create the pattern shown. What transformations did she use if parallelogram A is the pre-image and parallelogram B is the image?

Two angles are said to be coterminal if they locate the same point on the circumference.

This means that two angles are coterminal if they differ by a multiple of 360°: if you make a certain numbers of whole turns, in either direction, you end up in the same point.

So, you solve problems like this by adding or subtracting 360, until you are inside the interval [0,360].

In this case, you only need to add 360 once:

So, -315° and 45° are two coterminal angles.
