HW 10
Does anyone know how to do #4 or #8?
for # 4, draw in 4 altitudes to the outside lines. Then you get 4 equal pairs of triangles. Play with the congruent sides then.
for # 8, use the areas using sine. So the little triangle and big triangle share this same angle. Then use midpoints and similar tringle ratios to show how the lengths for the little triangle relate to the big triangle.
