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.
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 opposite the right angle is called the hypotenuse.
By using trigonometry that is applicable to a right angle 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.
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
You need either two sides given, to find a third side. Or > you need one side and an angle, to find another side.
The missing side of a right triangle is called the hypotenuse. This side is opposite the right angle and is the longest side of the triangle.
Of what?
Pythagorean Theorem: a2 + b2= c2 where c is the hypotenuse of a right triangle. Hypotenuse is the side of a right triangle opposite to the right angle.
no, it has one right angle. it would be a square with a side missing if it had 3 right sides.
If you have all three angles, you can use the law of sines, which states that the ratio of the sine of one angle is to it's opposite side as the sine of another angle is to it's opposite side.
Well, it depends. If you are trying to find the hypotenuse, then you go from the right angle and up. The side you across from right angle is the hypotenuse.
The study is called trigonometry.
Having sufficient angles or sides one can use either, The Law of Sines, or, The Law of Cosines. Google them.
use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side
You use the Pythagoras Theorem if it is a right-angled triangle. a squared + b squared = h (longest side, diagonal) squared, then square root h to find the longest side. if it is not a right angled triangle, then use the Sine or Cosine rule. Sine rule for: two angles and any one side or two sides and an angle that is not in between the sides. Cosine rule for: all three sides (but then you do not need to find a missing side) or two sides and an angle that is in between.
