Example Question #1 : Explain A Proof Of The Pythagorean Theorem And Its Converse: Ccss.Math.Content.8.G.B.6
How is the Pythagorean Theorem used?
The Pythagorean Theorem is used to solve for the area of a right triangle
The Pythagorean Theorem is used to solve for the volume of a triangle
The Pythagorean Theorem is used to solve for a missing side length of a right triangle
The Pythagorean Theorem is used to solve for a missing side length of a triangle
The Pythagorean Theorem is used to solve for a missing side length of a right triangle
The Pythagorean Theorem states that for right triangles, the square of the hypotenuse is equal to the sum of the square of the other two sides. In other terms:
With this equation, we can solve for a missing side length.
Example Question #1 : Explain A Proof Of The Pythagorean Theorem And Its Converse: Ccss.Math.Content.8.G.B.6
What is the formula associated with the Pythagorean Theorem?
The Pythagorean Theorem states that for right triangles, the square of the hypotenuse is equal to the sum of the square of the other two sides. In other terms:
In this equation:
Example Question #2 : Explain A Proof Of The Pythagorean Theorem And Its Converse: Ccss.Math.Content.8.G.B.6
How is the converse of the Pythagorean Theorem used?
To determine if a shape is in fact a triangle
To determine the a missing side length of a right triangle
To determine if a triangle is a right triangle
To determine the a missing side length of a triangle
To determine if a triangle is a right triangle
The converse of the Pythagorean Theorem is used to determine if a triangle is a right triangle. If we are given three side lengths we can plug them into the Pythagorean Theorem formula:
If the square of the hypotenuse is equal to the sum of the square of the other two sides, then the triangle is a right triangle.
Example Question #2 : Explain A Proof Of The Pythagorean Theorem And Its Converse: Ccss.Math.Content.8.G.B.6
Will the Pythagorean Theorem work to solve for a missing side length of a three sided figure?
No, the Pythagorean Theorem will only work to solve for the missing side length of a right triangle
No, the Pythagorean Theorem will only work to solve for the missing side length of a triangle
Yes, the Pythagorean Theorem is used to solve for any missing side length of a triangle
Yes, the Pythagorean Theorem is used to solve for any missing side length of at three sided figure
No, the Pythagorean Theorem will only work to solve for the missing side length of a right triangle
The Pythagorean Theorem can only be used to solve for the missing side length of a right triangle. Remember, the Pythagorean Theorem states that for right triangles, the square of the hypotenuse is equal to the sum of the square of the other two sides. In other terms:

Example Question #91 : Geometry
Can the Pythagorean Theorem be used to solve for the missing side length in the triangle provided?
Yes because the triangle is a right triangle
No because the triangle is not a right triangle
Yes because the triangle is only missing one side length
No because the triangle doesn't provide enough information
No because the triangle is not a right triangle
The Pythagorean Theorem states that for right triangles, the square of the hypotenuse is equal to the sum of the square of the other two sides. In other terms:
However, the triangle provided is not a right triangle because there is not an angle that is equal to
