1. Lesson 9.1
Concept: Identify rectangular and triangular prisms, and circular cylinders.
Guidelines: Prisms have bases that are polygons.
A cylinder is not a prism, because the circular bases are not polygons.
A flat surface of a prism that is a polygon is called a face or base.
Not a polygon, so not a face.

not a flat surface

2. Identify and describe the solid.4’ 2’
10’
Name it.
Rectangular Prism- because the base is a rectangular polygon.
How may faces?
6 faces
Height?
h = 4’ Height is the distance between the rectangular bases

3. Identify and describe the solid.2’
14’
Name it.
Cylinder- it has circles as bases, but it isn’t considered a prism without a polygon for a face.
How may faces?
No faces
Height?
h = 14’ Height is the distance between the circular bases

4. 3’ Identify and describe the solid. 15’ 5’ Name it.
Triangular Prism - because the base is a triangular polygon
How may faces?
5 faces
Height?
h = 15’ Height is the distance between the triangular bases

5. Sketch a rectangular prism with a base of 8 cm by 2 cm, and a height of 10 cm.

6. Sketch a triangular prism with a height of 11 cm and whose triangular base has a height of 9 cm and a base length of 7 cm.

7. Sketch a circular cylinder with a height of 17 cm and a radius of 4 cm.
