2D and 3D Shapes — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A sphere has 0 edges.
A sphere is completely round and has no edges.
2. A 3D shape with 2 circle faces and no corners is a cylinder.
A cylinder has 2 flat circular faces on top and bottom and no corners or vertices.
3. A hexagon has 3 more sides than a triangle.
A hexagon has 6 sides and a triangle has 3 sides, so 6 minus 3 equals 3 more sides.
4. A dice is shaped like a cube.
A dice has 6 square faces, 8 vertices, and 12 edges, just like a cube.
5. A shape with 6 sides and 6 corners is called a hexagon.
A hexagon is a 2D shape with exactly 6 sides and 6 corners.
6. A cone has 1 vertex.
A cone has 1 vertex, which is the point at the top.
7. A rectangle has 1 more sides than a triangle.
A rectangle has 4 sides and a triangle has 3 sides, so 4 minus 3 equals 1 more side.
8. An ice cream cone is shaped like a cone.
An ice cream cone has a circular opening and comes to a point at the bottom, just like a cone.
9. A rectangular prism has 8 vertices.
A rectangular prism has 8 vertices, which are the corner points where edges meet.
Part B: Match
Draw a line from each shape to the object it looks like.
1. Match each shape to a real-world object.
