FAST TRACK Cross sections and Rotation

​Cross Section and Rotation Review for FAST TRACK

When we slice a 3 dimensional object and pull it apart,

the cross section is the 2 dimensional shape created

​

Multiple Choice

Describe the cross section.

NOTICE the cross section is similar but not congruent to the base.

• triangle

• rectangle

• trapezoid

• square

Multiple Choice

What shape will the vertical cross -section of a cylinder be?

• Circle

• Triangle

• Rectangle

• Ellipse

Multiple Choice

What shape will the horizontal cross-section of a cone be?

• Dome

• Circle

• Pyramid

• Triangle

Multiple Choice

What shape does this cross section make?

• circle

• Trapezoid

• Rectangle

• Parallelogram

Multiple Choice

Describe the cross section.

• rectangle

• square

• oval

• circle

Multiple Choice

What shape will the vertical cross -section of a cylinder be?

• Circle

• Triangle

• Rectangle

• Ellipse

Multiple Choice

A two-dimensional cross section is taken of a three-dimensional object. If this cross section is a triangle, what can not be the three-dimensional object?

Multiple Choice

What is the cross section of the shape?

• Cone

• Triangle

• Pyramid

• Rectangle

When two dimensional shapes are rotated around an axis, they create a 3 dimensional object

​

It will help you if you visual the shape rotating around, since rotating will always make a circle, it is helpful to sketch its path

​
