# Math Help - 30-60-90 right triangle question

1. ## 30-60-90 right triangle question

how do distinguish a 30-60-90 from a 45-45-90 triangle?

The figure that you attached does not specify either 30-60-90 or 45-45-90 triangles. They may be 27-63-90 or 40-50-90, or whatever, The point is that the two angles 'a' and 'b' add up to 90.
