Have you ever wondered how to calculate the perimeter of an isosceles right triangle? It’s actually quite simple once you understand the properties of this unique shape.
An isosceles right triangle is a triangle with two sides of equal length and one right angle. To find the perimeter of this triangle, you just need to add up the lengths of all three sides.

The Perimeter of an Isosceles Right Triangle
Let’s say the two equal sides of the triangle are each 5 units long. To find the length of the hypotenuse (the third side), you can use the Pythagorean theorem. In this case, a^2 + b^2 = c^2 becomes 5^2 + 5^2 = c^2, which simplifies to 50 = c^2. Therefore, c = √50 or approximately 7.07 units.
Now, all you have to do is add up the lengths of the three sides: 5 + 5 + 7.07 = 17.07 units. So, the perimeter of an isosceles right triangle with two equal sides of 5 units each is approximately 17.07 units.
Remember, the perimeter of any triangle is simply the sum of the lengths of its sides. Understanding the properties of different types of triangles, like the isosceles right triangle, can help you solve geometry problems with ease.
Next time you come across an isosceles right triangle, you’ll know exactly how to calculate its perimeter. It’s a handy skill to have, whether you’re studying math or just curious about shapes and their properties.
