Sagot :

Pythagorean theorem is applied to the right-angled triangle. The length of the two legs of the triangle is 9√2 cm.

What is the Pythagorean theorem?

Pythagorean theorem helps us to find the hypotenuse of a right-angled triangle with the help of the other two sides of the triangle.

Hypotenuse² = Perpendicular² + Base²

Given to us

A right-angle triangle with angles, 45°- 45°- 90°

Length of the hypotenuse of the triangle, h = 18 cm

As in the given triangle, two of the angles are of equal measure, therefore, the triangle's two legs are of equal length, while the length of the hypotenuse is 18 cm.

AB = AC

Using the Pythagorean theorem,

BC² = AB² + AC²

18² = AB² + AB²

18² = 2 AB²

162 = AB²

AB = 9√2

Hence, the length of the two legs of the triangle is 9√2 cm.
