To identify each solid figure, we look at the shape of the bases and the sides. Here is the step-by-step identification:
1)
Hexagonal Pyramid: The base is a hexagon (6-sided polygon), and all side faces are triangles that meet at a single point at the top.
2)
Hexagonal Prism: It has two identical hexagonal bases on the top and bottom, connected by rectangular sides.
3)
Rectangular Prism: Also known as a cuboid. It has 6 faces that are all rectangles. The right-angle marks show the corners are square.
4)
Square Pyramid: The base is a square (indicated by the tick marks showing equal sides), and the sides are triangles meeting at a peak.
5)
Triangular Pyramid: Also called a tetrahedron. It has a triangular base and three triangular sides.
6)
Pentagonal Prism: It has two pentagon (5-sided) bases on the top and bottom, connected by rectangular sides.
7)
Sphere: A perfectly round ball shape with no flat faces or edges.
8)
Square Pyramid: Similar to #4, this has a square base and triangular sides.
9)
Cone: It has a circular flat base and tapers smoothly to a single point at the top.
10)
Cylinder: It has two identical circular bases on the top and bottom, connected by a curved surface.
11)
Rectangular Prism: Like #3, this is a box shape with rectangular faces. Even though it is tilted, the shape is the same.
12)
Triangular Prism: It has two triangular bases (front and back in this view) connected by three rectangular sides.
