If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.

How do you find the missing side from a right triangle?

to find the missing side of a right triangle you need the pythagorean theorem. A2 + B2 = C2. c is the longest side and a and b is the other sides. no particular side is a or b just the longest side is c.


How do you find a missing side on a triangle?

If you have at least 2 of the angle measurements and are trying to find the measurement of a missing angle you should do this: When you have the measurement of two angles, add them together. Then subtract the total from 180(always the sum of all of the triangle's angle's measurements). It will give you the measurement of the missing angle. If you are trying to find the length of the missing side, then use the Pythagorean theorem (a squared+b squared=c squared, c being the missing side) THIS ONLY WORKS FOR RIGHT TRIANGLES, however. first of all this didnt help me. second that therom is stupid cuz im only in 8th grade integrated algebra! get me a good answer jeez. i need to find the missing lenngth help me someone ---------------------------------------------------------------------- Honey, the thereom is the only way to get the right answer. And I'm in 7th grade, so get over the "you're only in 8th grade" I'm in 7th grade and understood what he said. I'd suggest using the answer he gave, 'cause that's the best you can get.


The side of a right triangle opposite the right angle?

The side opposite the right angle is called the hypotenuse.


What is the opposite side in a right triangle?

The opposite side of any angle in a triangle is the side that is not part of the angle. The side opposite the right angle is the longest side, called the hypotenuse.


How can you use ratios of the side lengths to find the angle measures of the acute angles in a right triangle?

By using trigonometry that is applicable to a right angle triangle.
