1 Name: Partners: Math Academy I ate: Review 2 Version A [A] ircle whether each statement is true or false. 1. Any two lines are coplanar. 2. Any three points are coplanar. 3. The measure of a semicircle is Two compelementary angles total An inscribed 100 angle defines a 50 arc. 6. Alternate exterior angles are supplementary. 7. The set of all points a given distance from a given point is a circle. 8. If a right triangle is inscribed in a circle, one of its sides is a diameter. 9. The arc length defined by a central 24 angle in a circle of radius r is (2πr). 10. A tangent to any point on a circle is orthogonal with the diameter to that point. 11. If a circle is inscribed within a square, each side of the square is tangent to the circle. 12. A central angle that defines an arc equal in length to the radius is slightly larger than 60. [B] The circle below has center A and radius 33. Find the stated measurements, and justify your answers with complete sentences. 1. the measure of AB 2. the length of B ( B 160 A

Use points (72 points per inch) for units. 1. [E] o the following to organize your group s reviews. 1. Make sure your name and your partners names are at the top of your review the first day. 2. Staple the reviews in order, all facing the same way. Put the staple in the very top left corner if everyone is finished or if the review is due; otherwise put the staple in the top right corner.
