4. This segment is formed when connecting the midpoints of two sides of a triangle. $100

5. What is a Midsegment Go to Scores

6. $200 This is the point where three or more lines, segments, or rays intersect.

7. $200 What is the point of concurrency Go to Scores

8. $300 What is an Orthocenter, Circumcenter, Centroid, and Incenter?

9. $300 Points of concurrency for altitudes, perpendicular bisectors, medians, and angle bisectors (respectively). Go to Scores

10. $400 Where are Circumcenters, Incenters, Centroids, and Orthocenters located?

11. $400 Circumcenters and Orthocenters's locations depend on the type of triangle formed. Acute triangles have the circumcenter and orthocenter inside. Right triangles have the circumcenter and the orthocenter located on the triangle. Obtuse triangles have the circumcenter and orthocenter outside the triangle. Incenters and Centroids are always located inside a triangle. Go to Scores

12. $500 Match the correct segment with its corresponding property 1. Perpendicular Bisectors 2. Medians 3. Midsegment 4. Angle Bisectors (a) (c) (b) (d)

13. $500 1. C 2. D 3. A 4. B Go to Scores

14. $100

15. Go to Scores WZ = 9

16. $200 Find the value of x (6x)ο (2x + 16)ο

17. $200 X = 4 Go to Scores

18. $300 A C D F G B E 8 6 Point D is the incenter of ΔABC. Find the value of FD.

19. $300 FD = 8 Go to Scores

20. $400 Is DA = DC? Explain. A B C D

21. $400 No, we do not know that DA is perpendicular to AB nor do we know that DC is perpendicular to BC. Go to Scores

22. $500 Find the value of x that makes N the incenter of the triangle.

23. $500 x = 6 Go to Scores

24. $100 List the sides and angles in order from smallest to largest. L K J 32ο

25. $100 Angles: L, K, J Sides: KJ, LJ, KL Go to Scores

26. $200 Is it possible to construct a triangle with side lengths of 1, 6, and 4? Explain why or why not.

27. $200 It is not possible, since the sum of any two sides should be greater than the last side. Since 1 + 4 is not greater than 6, a triangle can not be formed. Go to Scores

28. $300 What conclusion can be made about the triangles below? M S D A 95ο 98ο **Figures not drawn to scale

29. $300 AD > AM Go to Scores
