If the radius of a circle is perpendicular to a chord, 1. the radius bisects the chord and 2. right angles are created at the point where they meet.
Basically, for this question, all you have to do is make a smaller one and a larger one that is proportional to the original one. The small triangle could be 1/2 of the original, and the enlarged triangle could be double the original. It depends, as long as all of the triangles are proportional to each other.
Can you structure your question in a way that's more clear so i answer it for you?
