To find this you'll need to know the lengths of the other two (or possibly a couple of angles). The basic formula is Pythagorean Theorum is:
A (squared) + B (squared) = C (squared) with C being the longest side. Just
plug in the length of the two sides you know and solve for the third.

The perimeter of a triangle is 57 the first side is twice the length of the second side the third side is seven more than the second side what is the length of each side?
the perimeter of a triangle is 86 inches. the largest side is four inches less than twice the smallest side. the third side is 10 inches longer than the smallest side. what is the length of each side?
Is a 5cm by 12cm a right triangle?
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
How do you find a scale factor of a triangle?
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.
Triangle has two sides of length 4 and 15 What value could the length of the third side be?
The third side must be longer than 11 and shorter than 19.
The altitude of an equilateral triangle is 8cm . find the side?
The length of each side is 9.2376 cm. (rounded)
How do you find the side length of a right triangle if you have one side length?
One side is not enough. For a right triangle the third side can be calculated by Pythagoras' Theorem if you know the length of any two sides.
What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
A triangle has a perimeter of 42in the lengths of two sides of the triangle are 13in and 16in find the length of the third side?
13 in
What is formula of finding the perimeter of a triangle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
How do you find the length of the third side of a right angled triangle?
a2 +b2 = c2 (c is the longest side/or hypotenuse)
If one side of a triangle is 11 and the other side is 5 what is the minimum length of the third side?
The minimum third side length of a triangle having one side of 11 and another side of 5 is 6.
How do you find the midsegment of a triangle?
A midsegment of a triangle is parallel to the side of the triangle, and it's length is half the length of that side
What is the measure of the third side of an equiteral triangle have?
The length of the third side is the same as the length of either of the other two sides.
A radius of a regular triangle is 12 Find the length of one side of the triangle?
A radius of a regular triangle is 12 . find the length of one side of the triangle?
What equation do you use to find the adjacent side length of a triangle if you know the hypotenuse and the opposite side?
Third side = sqrt(hyp2 - opp2)
What is the length of the third side in 6.0 and 8.0?
If the third side is the hypotenuse of a right triangle, it is 10.0
HOW do you find the similar ratio of a triangle?
Divide the length of a side of one triangle by the length of the corresponding side of the other triangle.
