Which two triangles are similar? 48,69 Degrees, 48, 63 Degrees and 78, 63 degrees.
1 answer
If two triangles are to be similar, they must have all the same angle measurements. So, if every triangle has 3 angles with the sum of 180, you can easily find the missing angle by subtracting the 2 from 180. Do that with each possibility. Then see which ones have the 3 same numbers.
