Understanding the Isosceles Right Triangle

An isosceles right triangle is a special polygon featuring one 90-degree angle and two sides of identical length. This combination of a right angle and equal sides gives it a dual classification. Consequently, the two non-right angles are always equal, each measuring precisely 45 degrees.

The total sum of interior angles in any triangle is 180 degrees. Given the fixed 90-degree angle, the remaining 90 degrees are split equally between the other two angles. Therefore, the only right triangle that can also be isosceles is the 45-45-90 triangle.

Calculating the Hypotenuse: Formula and Method

The trusted Pythagoras theorem provides the foundation for finding the hypotenuse. This principle states that the square of the hypotenuse equals the sum of the squares of the other two sides. For an isosceles right triangle, where both legs are equal length 'B', the formula simplifies.

The Hypotenuse Formula

A² = B² + B² = 2B²
A = √(2B²) = B × √2

To solve for 'A', take the square root of both sides, resulting in the final formula: A = B × √2.

For example, if the equal sides measure 5 cm, the calculation is A = 5 × √2. This works out to approximately 7.071 cm. You can perform this calculation manually or use our free calculator for immediate results.

Frequently Asked Questions

Are all right triangles also isosceles triangles?

No, most right triangles are not isosceles. The only exception is the specific 45-45-90 triangle, where the two legs are congruent and the angles are 90, 45, and 45 degrees. This is the sole instance where the properties of a right triangle and an isosceles triangle intersect.

What is the step-by-step method to find the hypotenuse?

Follow these steps for a manual calculation. First, apply the Pythagorean theorem: A² = B² + B². Second, combine the terms to get A² = 2B². Finally, solve for A by calculating the square root: A = B × √2. The result is the length of the hypotenuse.
