No, the Pythagorean Theorem only works on right triangles.

You could use the law of cosines, though:

c^2=a^2+b^2-2ab*cos(C)

Where C is the measure of the angle between sides a and b.

Who developed the theory a plus b equals c?

A Mathematician named Pythagorean. That is why it is called Pythagorean's theorem. For every right triangle, this theorem will be true.


What is the only type of triangle the Pythagorean Theorem can be used on without being given any other measurements besides the sides?

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.


Does the theorem from the pythagorean theorem hold true if the triangle is not a right triangle?

No, it does not hold true unless the triangle has an angle of 90 degrees. In a triangle that is not a right triangle, there is no hypotenuse, just three different legs, so you cannot choose the square of one side to be equal to the squares of each of the other two sides.


The distance formula is derived from the Pythagorean theorem. true or false?

True


Is it true that Pythagorean theorem can only be used for right-angled triangles?

Yes. The Pythagorean Theorem is true for only right triangles. However, a variety of other similar equations can be used for other triangle types. Law of Sines: a/sinA = b/sinB = c/sinC Law of Cosines: c2 = a2 + b2 - 2ab*cosC


The side opposite the right angle in a right triangle is the hypotenuse.?

The hypotenuse is the longest side in a right triangle and it is opposite the right angle. It is always opposite the right angle and is found by using the Pythagorean theorem.


What is a famous math theory?

Do you mean THEOREM? In math a theorem is a statement which is proved true by applying a chain of logic. A famous one is the Pythagorean Theorem: The sum of squares of the legs of a right triangle equals the square of the hypotenuse. A^2 + B^2 = C^2


Is the Pythagorean theorem is true for all similar triangles?

Only right triangles.


Is it true that the law of cosines reduces the Pythagorean theorem with right triangles?

Yes


Do contractor use the pythagorean theorem?

Yes it is a way of checking a true right angle.


A2 plus b2 equals c2 is pythagoreans theorem?

A squared plus B squared equals C squared, where C is the hypotenuse of a right triangle and A and B are the other two sides is true and is one way of expressing the Pythagorean Theorem.


Is Pythagorean theorem is derived from the distance formula?

Yes, the distance formula for a line segment was derived from Pythagoras' theorem.
