Explain how you know that all right triangles with an acute angle measuring n° are similar to each other.
The angles in a triangle add up to 180. You know that one of the angles in a right angle triangle is 90. The other one you know is n. So the third angle is 180 - 90 - n. It doesn't matter how big the triangle is, if it's a right triangle and one angle is n, then the third angle is 180 - 90 - n. So, they are all similar.
