11. Given: J w K w ' K w M w , J w M w > K w L w M w L w i J w K w Prove: M w L w > J w K w Proof: Isosceles Triangles Page 216 Geometry Activity: Isosceles Triangles 1. / A > / B 2. They are congruent. 3. They are congruent. Page 219 Check for Understanding 1. The measure of only one angle must be given in an isosceles triangle to determine the measures of the other two angles. 2. W w X w > Z w X w ; / W > / Z 3. Sample answer: Draw a line segment. Set your compass to the length of the line segment and draw an arc from each endpoint. Draw segments from the intersection of the arcs to each endpoint. 4. / ADH is opposite A w H w and / AHD is opposite A w D w , so / ADH > / AHD . 5. B w H w is opposite / BDH and B w D w is opposite / BHD , so B w H w > B w D w . 6. Each angle of an equilateral triangle measures 60°. m / F 5 ¬ 3 x 1 4 60 5 ¬ 3 x 1 4 56 5 ¬ 3 x } 5 3 6 } 5 ¬ x m / G 5 ¬ 6 y 60 5 ¬ 6 y 10 5 ¬ y m / H 5 ¬ 19 z 1 3 60 5 ¬ 19 z 1 3 57 5 ¬ 19 z 3 5 ¬ z 7.
