Question

1. practice: organizing information

fill in the blanks to define a prism and its parts.
a prism is a ____ made of two ____ congruent polygons and all the points between them.

• bases: the two ______ congruent faces (like a top and bottom)
• lateral faces: all rectangles that are not ______ (like sides)
• altitude: the line segment whose length is the ______ of a prism

1. practice: using visual cues

a prism is named for its bases. identify the polygon bases. then name the prism.

1. practice: making mental images and drawing inferences

fill in the blanks.
compare a line segment and prism

• line segment: two points and all the ______ between them
• prism: two bases and all the ______ between them

1. practice: making mental images and drawing inferences

think about the shape of prisms to answer the questions.

1. why can any two opposite faces of a rectangular prism be called the bases?

Explanation:

A prism is a three - dimensional solid. Its bases are parallel and congruent. Lateral faces are non - base rectangles. Altitude gives the height. For naming prisms, we look at base polygons. A line segment has points in between two endpoints and a prism has points between its two bases. In a rectangular prism, opposite faces are congruent and parallel which is the property of bases.

Answer:

1. A prism is a three - dimensional solid made of two parallel congruent polygons and all the points between them.

• bases: the two parallel congruent faces (like a top and bottom)
• lateral faces: all rectangles that are not bases (like sides)
• altitude: the line segment whose length is the height of a prism

1. (Left - hand side figure):

• bases: triangles
• prism: triangular prism
• (Right - hand side figure):
• bases: rectangles
• prism: rectangular prism

7)

• Line segment: two points and all the points between them
• Prism: two bases and all the points between them

1. Any two opposite faces of a rectangular prism can be called the bases because they are parallel and congruent.
