Simply because the Pythagorean Theorem is not true for any triangle that
doesn't have a right angle in it. If a triangle has a right angle in it, then it
satisfies the Theorem. If it hasn't, then it doesn't.
And if it satisfies the Theorem, then it has a right angle in it, and if it doesn't,
then it hasn't.
60 degrees. There are 180 degrees in a triangle.
No, a triangle is the only polygon with three sides. All other polygons have four or more sides.
The interior angles of any shape besides a triangle will add up to 360 degrees.
An equilateral triangle, rhombus, or any regular polygon - pentagon, hexagon, heptagon, ...
An isosceles triangle has at least two equal sides and two equal angles An isosceles triangle has two or more congruent sides called legs. In an isosceles triangle with just two congruent sides, the angle formed by the legs is called the apex, and the other two angles, called base angles, are congruent. If the isosceles triangle has three congruent sides (AKA an equilateral triangle), then all three sides and angles are congruent, and there are no definitive base or vertex angles, besides...all of them.

I'm not sure what you are asking, so I may not be answering your question, but I'll try to the best of my ability.This is only for RIGHT TRIANGLESGiven a right triangle and the angle measurements besides the 90 degree angle of the right angle are 30 and 60 degrees (the combined angle measurements of a triangle always equal 180 degrees), the base is x, the height is xsqrt3, and the hypotenuse (or the longest side opposite the height) is 2x. This shortcut only works for right triangles with the other angle measurements 30 and 60 degrees.For example, you are given a triangle with the base=2 units. Using the shortcut, the height=2sqrt3 units. Then the hypotenuse=4 units.Given a right triangle and the angle measurements besides the 90 degree angle of the right angle are 45 and 45 degrees, the base is x, the height is also x, and the hypotenuse is xsqrt2. This shortcut only works for right triangles with both the other angle measurements equal to 45 degrees.For example, you are given a triangle with the base=2 units. The height is also 2 units. And finally, the hypotenuse=2sqrt2 units.*Another way to find the other side beside the shortcut is by using the Pythagorean Theorum (a2+b2=c2) if you are given the other two side measurements.*
Yes, as well as some Alegebra.
When working with metalwork measurements are to the hundredths frequently.
It would probably have been a trigon, but that is besides the point. The name triangle came first and was widely accepted. You also have quadrilateral rather than tetragon.
60 degrees. There are 180 degrees in a triangle.
Poles, Bermuda Triangle
I usually see ovarian cysts measured in millimeters.
As well as the the 3 sides of an equilateral triangle being equal in lengths so are its 3 interior angles equal in angles of 60 degrees.
They unified the Chinese language as well as all the measurements and built more roads.
