1
6
A hexagon has 6 sides and 6 vertices.
2
Triangle → 3 sides; Pentagon → 5 sides; Octagon → 8 sides; Quadrilateral → 4 sides
Triangle has 3, quadrilateral has 4, pentagon has 5 and octagon has 8 sides.
3
True
A cube has exactly 6 square faces, 12 edges and 8 vertices (corners).
4
Cone
A cone has a circular base and a single apex (point) at the top.
5
Sphere → No edges, no vertices; Cuboid → 6 rectangular faces; Cylinder → 2 circular faces, 1 curved surface; Triangular prism → 2 triangular faces, 3 rectangular faces
Each 3D shape has its own combination of flat faces, curved surfaces, edges and vertices.
6
False
All squares are rectangles, but not all rectangles are squares. A square must have all sides equal.
7
Rhombus
A rhombus has 4 equal sides but the angles are not necessarily 90 degrees.
8
6
A regular hexagon has 6 lines of symmetry - one through each vertex and one through each side's midpoint.
9
False
A tetrahedron has 6 edges. A triangular prism has 9 edges. So the prism has more, making the statement false.
10
4
A square has 4 lines of symmetry: 2 through midpoints of opposite sides and 2 through opposite corners.
