Line around which we can rotate a 3-Dimensional object.
Axis of Rotation
Which shape has 5 faces, 8 edges, and 5 vertices?
Square or Rectangular Base Pyramid.
What type of pyramid has no rotational symmetry?
Oblique (or irregular).
How many squares are in the top view:
4 (Four)
What would the depth scale of this object be if it was represented in a cabinet projection (how many centimetres)?
9 cm
A flat surface that divides a 3D object into two identical halves.
Plane of Symmetry
How many faces, edges, and vertices does a cylinder have?
2 faces, 2 edges, 0 vertices (+ 1 curved surface)
How many more planes of symmetry does a regular right prism have than lines of symmetry of its base (other than a cube)?

Isometric Grid Paper
Which shape has 7 faces, 5 equal length edges on its base(s), 15 total edges, and 10 vertices? (Be specific)
Regular Pentagonal Base Prism.
As a cube rotates on its axis of rotation, it appears to look the same at 90 degrees, 180 degrees, 270 degrees, and 360 degrees. It therefore has _____-____ axis of rotational symmetry.
Four-fold.
How many total combined squares are in the top and front views:
11 (Eleven)
What would the length of this object be with a scale of 1 interval = 10m?
40 m
Used to translate base shapes in perspective drawing.
Depth Scale (half of the base scale is often used to create a realistic perspective).
Which shape has 7 faces, 6 unequal length edges on its base(s), 12 total edges, and 7 vertices? (Be specific)
Irregular Hexagonal Base Pyramid.
How many planes of symmetry does a cube have?
9 (Nine)
What is the minimum number of blocks in this shape? How do you know?
9 (Nine). No faces of the block in the back left corner on the bottom row are visible, therefore we do not know for sure that there is a block there.
What shape is represented in this cabinet drawing?
Base scale: 1 interval = 2m.
Depth Angle: 45 Degrees
Depth Scale: 3 over, 3 up = 2m
A cube (2m x 2m x 2m)
