Pythagorean Theorem and Their Converse

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

• It is used in construction, navigation, and various fields to calculate distances.

• It is primarily used in algebra to solve equations.

• It is a theorem that only applies to theoretical mathematics.

• It is used to calculate the area of circles.

Which is the Pythagorean theorem?

• c² = a² + b²

• a² + b² = c

If a triangle has sides of lengths 5, 12, and 13, is it a right triangle?

• Yes, because 5² + 12² = 13².

• No, because the sides do not satisfy the Pythagorean theorem.

• Yes, but only if the triangle is isosceles.

• No, because the longest side is not the hypotenuse.
