Question
the cross section of a solid figure sliced perpendicular to its base is shown.
trapezoid image
decide whether or not the cross section could have come from each of the figures listed below
| yes | no | |
|---|---|---|
| cylinder | unselected yes | selected no |
| square pyramid | selected yes | unselected no |
| rectangular prism | selected yes | unselected no |
| cone | unselected yes | selected no (with hand icon) |
Step1: Analyze Triangular Prism
A triangular prism, when sliced perpendicular to its base (which is a triangle), can have a trapezoidal cross - section. If the slice is not parallel to the lateral faces in a way that would give a triangle or a rectangle, a trapezoid is possible. So the 'Yes' selection for triangular prism is correct.
Step2: Analyze Cylinder
A cylinder, when sliced perpendicular to its base (a circle), will have a rectangular cross - section (if sliced vertically) or a circle (if sliced horizontally). It cannot have a trapezoidal cross - section. So the 'No' selection for cylinder is correct.
Step3: Analyze Square Pyramid
A square pyramid, when sliced perpendicular to its base (a square) and not through the apex, can have a trapezoidal cross - section. The sides of the trapezoid would be formed by the slant edges of the pyramid. So the 'Yes' selection for square pyramid is correct.
Step4: Analyze Rectangular Prism
A rectangular prism, when sliced perpendicular to its base (a rectangle) at an angle that is not parallel to the faces, can result in a trapezoidal cross - section. So the 'Yes' selection for rectangular prism is correct.
Step5: Analyze Cone
A cone, when sliced perpendicular to its base (a circle), will have a triangular cross - section (if sliced through the apex) or a circular segment - like shape, but not a trapezoid. So the 'No' selection for cone is correct.

The selections made (triangular prism: Yes, cylinder: No, square pyramid: Yes, rectangular prism: Yes, cone: No) are correct based on the cross - sectional properties of each solid.
