State the converse of the Pythagorean theorem in the context of a construction project.

• If a right-angled triangle is used in a construction project, then the square of the length of the longest side is equal to the sum of the squares of the other two sides.

• If a right-angled triangle is used in a construction project, then the square of the length of the longest side is not equal to the sum of the squares of the other two sides.

• If a triangle is not a right triangle in a construction project, then the square of the length of the longest side is equal to the sum of the squares of the other two sides.

• If a triangle is not a right triangle in a construction project, then the square of the length of the longest side is not equal to the sum of the squares of the other two sides.

Explain how you can determine if a triangle is a right triangle using the Pythagorean theorem.

• If a ladder is leaning against a wall and the distance from the base of the ladder to the wall and the length of the ladder form a right triangle, then the triangle is a right triangle.

• If a flagpole is standing upright and the height of the flagpole and the shadow it casts on the ground form a right triangle, then the triangle is a right triangle.

• If a ramp is placed against a truck and the length of the ramp and the height of the truck form a right triangle, then the triangle is a right triangle.

• If a wire is stretched across two poles and the distance between the poles and the length of the wire form a right triangle, then the triangle is a right triangle.
