Example Question #2 : How To Find The Perimeter Of A 45/45/90 Right Isosceles Triangle
What is the perimeter of a right isosceles triangle that has leg lengths of 
Recall how to find the perimeter of a triangle:
Now, because this is a right isosceles triangle, we know the following:
From the information given in the question, we already have two of the sides needed. Now, recall the Pythagorean Theorem to find the third side of the triangle, the hypotenuse.
The Pythagorean Theorem can then be simplifed to the following equation:
Now, solve for 
Now, plug in the given value for 
Now that we have all three sides of the triangle, we can find the perimeter. Use a calculator and round to
