4.6 Isosceles Triangles and Right Triangles Goal 1: How to use properties of isosceles triangles to solve problems Goal 2: How to use properties of right triangles to solve problems in geometry In lesson 4.1, you learned that if an isosceles triangle has exactly two Congruent sides, then these sides are the legs of the triangle, and the noncongruent side is the base. The two angles that have the base as one side are the base angles. Leg Leg Base angles Base

4.6 Isosceles Triangles and Right Triangles Base Angles THM If two sides of a triangle are congruent , then the angles opposite them are congruent. C N H Statements Reasons Y QED

4.6 Isosceles Triangles and Right Triangles If two angles of a triangle are congruent, then the sides opposite them are congruent.

4.6 Isosceles Triangles and Right Triangles If a triangle is equilateral, then it is also equiangular.

4.6 Isosceles Triangles and Right Triangles If a triangle is equiangular, then it is also equilateral.

4.6 Isosceles Triangles and Right Triangles HL Congruence THM If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of a 2nd right triangle, then the two triangles are congruent.
