Find the square root of one side squared plus the second side squared.
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
By using Pythagoras' theorem.
Really you don't have enough data to calculate this.The height is not necessarily one of the three sides. The height is perpendicular to the width.If the triangle has a right angle, and you know two of the sides, you can calculate the third side using the rule of Pythagoras (a squared + b squared = c squared).Really you don't have enough data to calculate this.The height is not necessarily one of the three sides.

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.
Triangle
If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.
If you know two sides of a right triangle, the Pythagorean Formula lets you find the third side. Also, if you know all three sides of a triangle, you can confirm whether it is, or isn't, a right triangle.
If you know the lengths of two sides then use Pythagoras' theorem to find the third side.

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.
To get the perimeter, you need to add all three sides. I assume you can get the third side by inserting the numbers you know into Heron's formula.
The Pythagorean theorem is a2 + b2 = c2. It is used for right triangles. If you know two of the sides, you can use the theorem to find the third side.
If it has an hypotenuse then it is a right angle triangle and if you know its angles then use trigonometry to find its other two sides.
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
If you know the length of 2 sides of a triangle, you can always find the length of the third using Pythag. Pretty neat!
Measure two of them. Then the third is 180 degrees minus the two that you know. Or measure the lengths of the sides and use the cosine rule.
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.
