What is the converse of the Pythagorean Theorem?

The converse states that if in a triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle.

How do you find the area of a right triangle?

The area of a right triangle can be found using the formula: $$Area = \\frac{1}{2} \\times base \\times height$$ .

What is the formula for the perimeter of a right triangle?

The perimeter of a right triangle is the sum of the lengths of all three sides: $$Perimeter = a + b + c$$ .

If a right triangle has a hypotenuse of 15 and one leg of 9, what is the length of the other leg?

Using the Pythagorean Theorem: $$9^2 + b^2 = 15^2$$ , which simplifies to $$81 + b^2 = 225$$ , so $$b^2 = 144$$ , thus $$b = 12$$ .

What is the significance of the Pythagorean Theorem in real life?

The Pythagorean Theorem is used in various fields such as architecture, construction, navigation, and physics to calculate distances and angles.

What is the formula to find the length of the diagonal of a rectangle?
