You need to know the angle between them.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
The answer depends on what information you have about the other sides and angles.
You add the 2 other sides together, then minus that number off 180.
An isosceles triangle has 3 sides 2 of which are equal in length
It depends on how big the triangle is. Find out the length of one side and then all the rest of the sides will be the same.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
The answer depends on what information you have about the other sides and angles.
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
subtract the two sides that you know from the perimeter to get the unknown side.
Given the lengths of two sides of a right triangle, you can find the length of the other side.
Measure it with a rule or find its perimeter and subtract the other 2 sides from it
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.
You add the 2 other sides together, then minus that number off 180.
An isosceles triangle has 3 sides 2 of which are equal in length
It depends on how big the triangle is. Find out the length of one side and then all the rest of the sides will be the same.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
Two sides of an isosceles triangle are equal. The base is the other side.
