A triangle with at least two sides of equal length is called an isosceles triangle.
the family group of the triangle is percussion.
No one. A triangle is not a theory. The mathematics of a triangle are not theories they are facts. Some people that showed this to be so are Pythagoras and Euclid.

Yes. In fact, a triangle must have at least two acute angles.
