Visualizing Pyramid Cross-Sections

What is the apex of a pyramid?

• The midpoint of the base

• The highest vertex where all faces meet

• The base of the pyramid

• A type of edge

What is the role of vertices in a solid?

• The base of the solid

• Lines where planes intersect

• Points where edges meet

• None of the above

What does a slicing plane create when it intersects a solid?

• A three-dimensional shape

• A vertex

• A curved line

• A two-dimensional figure

If a cross-section intersects four faces of a pyramid, how many edges will it have?

• Five

• Four

• Six

• Three

What shape is the cross-section through the apex of a pyramid?

• Triangle

• Circle

• Rectangle

• Square

How many edges does a cross-section have if it intersects five faces?

• Four

• Five

• Six

• Seven

What shape results from a horizontal cross-section of a pyramid with a square base?

• Triangle

• Circle

• Square

• Rectangle

What is a common misconception about cross-sections?

• They can only be horizontal

• They must intersect all faces

• They can only be vertical or horizontal

• They do not intersect the base

What geometric property do horizontal cross-sections of a pyramid share with the base?

• They are always triangular

• They are larger than the base

• They are smaller but of the same shape

• They are of the same shape but different size

What is the shape of the base of the pyramid discussed in the lesson?

• Triangle

• Square

• Rectangle

• Circle
