This side will always be the longest side of the right triangle. The other two shorter sides are called legs. The Pythagorean Theorem states that if you add the squares of the lengths of the two legs of a right triangle you will always obtain the square of the length of the hypotenuse. Let a and b be the lengths of the two legs of a right triangle and let c be the length of the hypotenuse. Consider the right triangle shown below. Find the value of x.
First notice that the lengths of the two legs are 4 and 3. The length of the hypotenuse is x. Using the letters from the Pythagorean Theorem, we have. Now try one by yourself. If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

Thus, with the help of the Pythagorean theorem, the Hypotenuse leg theorem was proved, which says that if the hypotenuse and one leg of one right triangle are congruent to the other right triangle's hypotenuse and leg side, then the two triangles are congruent.
In a right-angled triangle, the side opposite to the right angle is called the hypotenuse and the two other adjacent sides are called its legs. The hypotenuse is the longest side of the triangle, while the other two legs are always shorter in length. The hypotenuse leg theorem states that if the hypotenuse and one leg of one right triangle are congruent to the other right triangle's hypotenuse and leg side, then the two triangles are congruent. According to the Pythagorean theorem, in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
It is justified when the two sides and an angle not included between them of a triangle are respectively equal to two sides and an angle of another triangle. When any two values are known, we can apply the theorem and calculate the missing values. Hypotenuse Leg Theorem In a right-angled triangle , the hypotenuse is the longest side which is always opposite to the right angle. Hypotenuse Leg Theorem 2. Hypotenuse Leg Theorem Proof 3.
