What is the formula to find the length of a missing side in a right triangle?

The formula is $$a^2 + b^2 = c^2$$ , where c is the hypotenuse.

If a triangle has sides of lengths 7, 24, and 25, is it a right triangle?

Yes, because $$7^2 + 24^2 = 25^2$$ (49 + 576 = 625).

What is the value of c if a = 9 and b = 12 in a right triangle?

Using the Pythagorean Theorem: $$c = \\sqrt{9^2 + 12^2} = \\sqrt{81 + 144} = \\sqrt{225} = 15$$ .

What happens if a triangle does not satisfy the Pythagorean Theorem?

If a triangle does not satisfy the Pythagorean Theorem, it is not a right triangle.

What is the significance of the right angle in a right triangle?

The right angle (90 degrees) is crucial as it defines the triangle as a right triangle and allows the use of the Pythagorean Theorem.

If a triangle has sides of lengths 10, 24, and 26, is it a right triangle?

Yes, because $$10^2 + 24^2 = 26^2$$ (100 + 576 = 676).

What is the hypotenuse in a right triangle with legs of lengths 5 and 12?

The hypotenuse is $$\sqrt{5^2 + 12^2} = \sqrt{25 + 144} = \sqrt{169} = 13$$ .

Can the Pythagorean Theorem be used for non-right triangles?

No, the Pythagorean Theorem only applies to right triangles.
