Explanation:
Let’s go step by step to solve this task. The goal is to figure out what 2D shape you get when you slice each 3D shape either horizontally or vertically.
We’ll look at each 3D shape one by one and think about what the cross-section looks like.
1.
Cone
- If you slice it
horizontally (parallel to the base), you get a
circle.
- If you slice it
vertically (through the pointy top and the center of the base), you get a
triangle.
2.
Cylinder
- If you slice it
horizontally, you get a
circle (same as the base).
- If you slice it
vertically, you get a
rectangle (the height of the cylinder and the diameter of the base).
3.
Triangular Prism
- If you slice it
horizontally, you get a
triangle (same as the base).
- If you slice it
vertically, you get a
rectangle (because the sides are rectangles).
4.
Rectangular Prism
- If you slice it
horizontally, you get a
rectangle (same as the base).
- If you slice it
vertically, you get a
rectangle (the side shape).
5.
Square Pyramid
- If you slice it
horizontally, you get a
square (smaller than the base, but still a square).
- If you slice it
vertically through the pointy top and the center, you get a
triangle.
Now let’s fill in the table based on this:
| 3D Shape | Horizontal Cross Section | Vertical Cross Section |
|------------------|--------------------------|------------------------|
| cone | circle | triangle |
| cylinder | circle | rectangle |
| triangular prism | triangle | rectangle |
| rectangular prism| rectangle | rectangle |
| square pyramid | square | triangle |
Final Answer:
The completed table shows the 2D shapes formed by horizontal and vertical cross-sections of each 3D shape. The answers are as listed above.
