Given the 2 sets of figures below, are the pairs of triangles similar for both set a and set b? Why or why not? What is the similarity statement and the scale factor?
The left triangle has angles of:
The last angle can be calculated as:
The right triangle has angles of
The scale can be calculated as:
If they were similar, they would have to have 3 pairs of equal angles. In these triangles there is only one pair of equal angles:
