Two names for a triangle are "scalene triangle" and "isosceles triangle." A scalene triangle is a triangle with three unequal sides, while an isosceles triangle is a triangle with at least two equal sides. These names are based on the measurements of the sides of the triangle and help classify different types of triangles based on their properties.
An isosceles triangle
a scalene triangle a scalene triangle
Isosceles triangle
It is an isosceles triangle.
A triangle with at least two sides of equal length is called an isosceles triangle.
Pythagoras, or at least he invented and found out everything about the right-angled triangle. The other triangles creators are anonymous, probably created before humans as we know them today lived. It's possible that it was discovered as a triangle by neanderthals who were scratching on the walls. Thanks. The properties of the triangle were known by the ancient Greeks and earlier civilizations.

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