Exploring Right Triangles and the Pythagorean Theorem

A ladder is leaning against a wall. The foot of the ladder is 6 feet away from the wall, and the ladder reaches a height of 8 feet on the wall. Is the ladder forming a right triangle with the wall and the ground?

• Yes, the ladder is forming a right triangle with the wall and the ground.

• No, the ladder is leaning too steeply to form a right triangle.

• No, the ladder is not forming a triangle at all.

• Yes, but the ladder is too short to reach the wall.
