Answer: Choice 1) triangle DEF is similar to triangle BAC because corresponding angles are congruent. Ratio is 1/2
D = 53, B = 53 are two angles that are congruent and pair up.
So are E = 58 and A = 58. They pair up as well.
Finally, F = 69 and C = 69 pair up
We get triangle DEF is similar to triangle BAC. The order of the letters matters.
If we start with triangle BAC, and cut each side in half, then we get the corresponding sides of triangle DEF. For example, BA = 6.2 goes to DE = 3.1
