how do i determine whether 27, 120, 123 are the measures of the sides of a right angle....and after that then state whether they form a Pythagorean triple?????......PLEASE HELP:)
1) Triangle Inequality 2) Pythagorean Theorem
??
I misread you question at first. I thought they wanted to know if it was a triangle, then was it a right triangle. We can do it in one step. Does a^2 + b^2 = c^2 ring a bell?
yea thats the Pythagorean theorem.....thats ho you find the missing side of a triangle
It can also be used to prove. If your three numbers can be substituted in to make a true equation, then the triangle with those sides is a right triangle.
for it to be a right triangle the angle has to equal exactly 90 degrees
The largest angle would have to be 90 degrees and would have the longest side opposite from it. We can be sure of one angle being 90 degrees once we prove that squaring each of the smaller sides and adding them equals the square of the longest side.
