[4] 7.25
[5] 13º; 50º
[6] The figure is not a polygon because not all sides are segments.
[7] The figure is not a regular polygon because it is not equiangular.
[8] 7
[9] Sample answer:
[10] OU , OR, or OT
[11] Sample answer: A chord intersects the circle at two points, whereas the tangent only
intersects at one point.
[12] [B]

[20] congruent
[21] x  49
[22] 78°
[23] x  5
[24] No
[25] Lines l and m should not be marked parallel because the sum of the two angle measures
shown would have to add to 180 for the lines to be parallel and they do not.

[40] x  21
[41] By the Triangle Inequality Conjecture, the sum of 17 cm and 31 cm should be greater than
54 cm. To correct this, QP and/or PR should be increased to represent possible values of side
lengths for QPR.
