the figure shows three right triangles. triangles abd, cad, and cba are similar.

theorem: if two triangles are similar, the corresponding sides are in proportion.

using the given theorem, which two statements to prove that if segment bc is x, then x2 = 74?

1) segment bc ⋅ segment dc = 49

segment bc ⋅ segment bd = 35

2) segment bc ⋅ segment dc = 49

segment bc ⋅ segment bd = 25

3) segment bc ⋅ segment dc = 25

segment bc ⋅ segment bd = 35

4) segment bc ⋅ segment dc = 25

segment bc ⋅ segment bd = 49
