The pyramid builders of ancient Egypt certainly knew about the 3-4-5, as they used a wooden version to measure right angles.
Right angled triangles!
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
Right-Angle triangles
Only right triangles.
The congruence theorems for right triangles are the Hypotenuse-Leg (HL) theorem and the Leg-Acute Angle (LA) theorem. The HL theorem states that if the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent. The LA theorem states that if one leg and one acute angle of one right triangle are congruent to one leg and one acute angle of another right triangle, then the triangles are congruent.
It was Pythagoras and his theorem about right angle triangles.
The Babylonians and Indians were the first to study the angles and features of special right triangles. This occurred long before Pythagoras and his followers were credited with the discovery.
He discovered it in Greece.
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
Right angled triangles!
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
your mom is the right triangles

Right angled triangles do!
squares, right triangles, rectangles
