This is a right triangle; when you sum the squares of the lengths of the sides, you get the square of the length of the hypotenuse. Incorrect. This is not a right triangle, so you cannot use the Pythagorean Theorem to find r. The correct answer is Triangle B.
How do you use the Pythagorean Theorem to find right triangles?
Key Points
- The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
- In a right triangle, one of the angles has a value of 90 degrees.
- The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.
Can you use Pythagorean Theorem on any triangle?
Pythagoras’ theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.
What does the Pythagorean Theorem help you find?
The Pythagorean Theorem is a statement in geometry that shows the relationship between the lengths of the sides of a right triangle – a triangle with one 90-degree angle.
Can you use the Pythagorean Theorem on an isosceles triangle?
The Pythagorean theorem can be used to solve for any side of an isosceles triangle as well, even though it is not a right triangle. Isosceles triangles have two sides of equal length and two equivalent angles. Draw a straight line down the middle of the triangle from the vertex to the base.
When would you use Pythagorean Theorem in real life?
Architecture and Construction. Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof.
What if you only know the hypotenuse?
If all you have is the length of the hypotenuse, there is no way to find the length of the legs. With that length for the hypotenuse, there is an infinite number of different right triangles. If the angles are 45, 45, and 90 degrees, the triangle is half of a square. The two legs are the same length.
When do you use the Pythagorean theorem?
You use the Pythagorean Theorem when you know the lengths of two sides of a right triangle and you want to figure out the length of the third side. The legs are the two short sides that touch the right angle, and the hypotenuse (the longest side) is opposite the right angle.

What is the formula for the Pythagoras triple?
The sides of a right triangle (say x, y and z) which has positive integer values, when squared are put into an equation, also called a Pythagorean triple. “c” is the hypotenuse side. According to the definition, the Pythagoras Theorem formula is given as:
Which is the longest side of the Pythagoras theorem?
“c” is the hypotenuse side. According to the definition, the Pythagoras Theorem formula is given as: The side opposite to the right angle (90°) is the longest side (known as Hypotenuse) because the side opposite to the greatest angle is the longest.
