Geometry Chapter 4 Review Name:_________________________________ 1. What are the lengths of the sides of this equilateral triangle? Use the figure for Questions 2 – 54 2. What is m∠1? 3. What is m∠2? 4. What is m∠3? 5. If △DJL ≅ △EGS, which segment in △EGS corresponds to ̅̅̅̅ 𝐷𝐿 ? 6. What is the congruency statement of the triangles? 7. Given that KML CBA, find the value of x. 8. Quadrilateral MNQP is made of two congruent triangles. ̅̅̅̅ 𝑁𝑃 bisects ∠N and ∠P. In the quadrilateral, m∠N = 50 and m∠P = 100. What is the measure of ∠M? 9. Find the value of x. 10. Write a correct congruence statement for the triangles shown. Decide whether it is possible to prove that the triangles are congruent. If it is possible, name the correct reason. Some problems may have more than one answer – name all that apply. If it is not possible to prove the triangles are congruent with the given information, say “not possible.” 11. L 12. 13. P O 14.
