An image of a rectangular pyramid is shown below:

A right rectangular pyramid is shown.

Part A: A cross section of the rectangular pyramid is cut with a plane parallel to the base. What is the name of the shape created by the cross section? Explain your answer.

Part B: If a cross section of the rectangular pyramid is cut perpendicular to the base, passing through the top vertex, what would be the shape of the resulting cross section? Explain your answer.

Answer 1

A: Square

B: Triangle

Explanation:

A: just bring the base and you still have a square as the base. That's the same as a "cross section"

B: like a scanning laser scanning up and down, when the laser scanner reaches the middle...pretend it cuts the pyramid. You'd have a triangle on the cut side.
