what is ratios of corresponding side lengths

Question

Make a triangle that is larger than  angles 100°,60°,and 20° and has the same measures. Find the ratio of the corresponding side lengths.

Answer 1

Any 2 triangles with the same 3 angle measures (that is, all three sets of corresponding angles are congruent) are SIMILAR triangles.  They have the same shape, if not the same size.  Therefore the ratios of the corresponding side lengths will all be equal.

 

It looks like you are in the process of learning the AAA triangle similarity theorem.
