1. angle angle similarity

2. 47° 58° 75° 58° 75° Are the following triangles similar? E D F B A C <C and <F have the same measure, so they are congruent. 180 – 58 - 47° = 75° <E = 75° So how do I know the following triangles similar? Since 2 angles of ΔABC are congruent to 2 angles of ΔDEF, the 2 triangles are similar.

3. How tall is the flagpole? 3.5 ft 8 ft h ft 35 ft 3.5 h 8 35 = 3.5  35 = 8  h 122.5 = 8  h h = 15.3125 ft
