Prism Slicing and Shapes

This video tutorial by Mr. Holcomb covers lesson 16 on slicing right rectangular prisms. It begins with an introduction to the topic, followed by examples of slicing a sphere and a rectangular prism. The tutorial explains the properties of slices, including parallel and perpendicular slicing. It includes group discussions and practical exercises to reinforce the concepts. The lesson concludes with a summary and problem set for further practice.

What shape is formed when a plane slices through a sphere?

• Square

• Triangle

• Circle

• Rectangle

When a right rectangular prism is sliced parallel to one of its faces, what is true about the resulting slice?

• It is a circle

• It is identical to the face it is parallel to

• It is a triangle

• It is a different shape

If a slice is perpendicular to the base of a right rectangular prism, what angle does it form with the base?

• 180 degrees

• 60 degrees

• 90 degrees

• 45 degrees

Which faces are perpendicular to a slice that is parallel to the top and bottom of a right rectangular prism?

• None

• Front and back

• Left and right

• Top and bottom

In a right rectangular prism, if a slice is made parallel to a face, what can be said about its dimensions?

• They are unrelated to the face

• They are the same as the face

• They are larger than the face

• They are smaller than the face

What is the relationship between the dimensions of a slice and the dimensions of the prism when the slice is parallel to a face?

• The slice is always smaller

• The slice is always larger

• The slice is unrelated

• The slice has the same dimensions

When a slice is perpendicular to a face of a prism, what is the shape of the slice?

• Rectangle

• Hexagon

• Circle

• Triangle

If a slice is made perpendicular to the top face of a prism, which other face is it also perpendicular to?

• Right face

• Bottom face

• Front face

• Left face

What is the height of a slice that is perpendicular to the base of a prism?

• Equal to the height of the prism

• Equal to the length of the base

• Equal to the width of the base

• Equal to the diagonal of the base

How can you determine if a slice in a prism is a rectangle?

• If all angles are right angles

• If it has three sides

• If it is a circle

• If it is a parallelogram
