Question

1. You have a solid rectangular pyramid made of dough. Consider the cross sections that are formed when you

slice into the cube as described. Draw each slice and describe the resulting cross section (2 points each)

(a) A slice that cuts parallel to the base

(b) A slice that cuts perpendicular to the base through the vertex Triangle

(c) A slice that cuts perpendicular to the base but NOT through the vertex,

Answer 1

a) will show a cross section of either a SQUARE or RECTANGLE depending on if the pyramid is either a square or a rectangular pyramid

b) will show a cross section of a TRIANGLE,

c) will show a cross section of a TRAPEZOID

Explanation:

(a) A slice that cuts parallel to the base will result into either a SQUARE or a RECTANGLE (depends on the length of the 4 sided base).

b) A slice that cuts perpendicular to the base through the vertex Triangle will result in a TRIANGLE.

(c) A slice that cuts perpendicular to the base but NOT through the vertex will result in a TRAPEZOIDAL SECTION.
