6.5 - Isosceles and Equilateral Triangles Recap: If two sides of a triangle are congruent, then the angles opposite those sides are also congruent by the Isosceles Triangle Theorem. If two angles of a triangle are congruent, then the sides opposite the angle are congruent by the Converse of the Isosceles Triangle Theorem. Equilateral triangles are also equiangular. Examples: 509 8. Find the value of x and y X - 46.6 - Congruence in Right Triangles Recap: If the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent by the Hypotenuse-Leg (HL) Theorem. Examples: Write a proof 9. Given: LN 1 KM, KL=ML; Prove AKLNEAMLN K N M6.7 - Congruence in Overlapping Triangles Recap: To prove overlapping triangles congruent, you look for the common or shared sides and angles. Example: Separate and redraw the overlapping triangles. m 10. D n
