Answer Key
Lesson 5.6
Study Guide
1. 5; Two sides of the first triangle are congruent to two sides of the second triangle, and the third side of the first triangle is neither longer nor shorter than thethird side of the second triangle. So, by the Converse of the Hinge Theorem, the included angle of the firsttriangle is neither longer nor shorter than the included angle of the second triangle.
2. <; Because }
AD > }
BC , } BD > } BD , and m∠ADB < m∠CBD, then by the Hinge Theorem, AB < CD.
3. You and your friend are the same distance from the tree.
