1. In is the _____. A. altitude B. median C. all of these D. perpendicular bisector Hint 2. Is an altitude of Explain. A. No; because is not amedian of B. Yes; because is aperpendicular bisectorof C. Yes; because has oneendpoint at vertex andis perpendicular to D. No; because isoutside Hint 3. Which theorem or postulate states that if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and corresponding leg of another right triangle, then the triangles are congruent? A. LA Theorem B. LL Theorem C. HA Theorem D. HL Postulate Hint 4. Which additional information is needed to prove by the HA Theorem? A. B. C. D. Hint 5. Which problem-solving strategy is used in indirect proofs? A. draw a diagram B. guess and check C. decision-making D. working backward Hint 6. The _________ segment from a point to a line or plane is the shortest segment from the point to the line or plane. A. integral B. perpendicular C. consecutive D. parallel Hint 7. Refer to the figure. Is longer than Explain. A. Yes; the measure of the angle opposite is 90 and the measure of the angle opposite must be less than 90 because the sum of the measures of the angles must be 180. B. Yes; the shortest distance from a point to a line is a perpendicular segment. C. All of these. D. Yes; is the hypotenuse of and is a leg. Hint 8. Is it possible to draw a triangle with sides measuring 13, 21, and 39? Explain A. No; 39 is greater than 13 + 21. B. No; 13 is less than 21 + 39. C. Yes; the sides of the triangle are not all the same lengths. D. Yes; 13 + 21 is less than 39. Hint 9. Marty has a piece of rope with exactly 7 knots tied at equal intervals as shown. Using the rope, he wants to make triangles so that each vertex of the triangle occurs at a knot. How many different triangles can Marty make? A. 3 B. 2 C. 4 D. 1 Hint 10. In the figure, is a median in and Which statement is always true? A. If then RS < TS. B. If then C. If then is acute. D. x = 12 Hint 11. a > b means that ___________. A. a = b + c, for some positive number c B. a b C. a + c = b, for some positive number c D. a + b = 0 Hint 12. is a median of PRS. Which statement is true? A. mQTS > mQTP B. C. mQTS < mQTP D. PTR and STR are complementary. Hint
