I put the wrong angle measure on my earlier question. It should have been... How many different triangles, if any, can be drawn with on 20 degree angle, one 45 degree angle, and one 115 degree angle.
Thanks....

• math -

well, the three angles are given, so that defines the "shape" of the triangle.

All that's left is specifying the size. Many many triangles can be drawn, depending on the length of the sides.

Think of squares. they all have 4 90° angles, but there are squares of any size. Same with a given set of angles for a triangle.

In some sense, there is only one such triangle, since all the rest are similar.
