Solid Geometry and Representations of Three-Dimensional Figures

Front

What is a cross-section in geometry?

Back

A cross-section is the intersection of a solid object with a plane, resulting in a 2D shape.

Front

What shape is formed by the horizontal cross-section of a cylinder?

Back

Circle.

Front

What is the vertical cross-section of a cube?

Back

Square.

Front

Identify the resulting 2D cross-section from a sliced triangular prism.

Back

Triangle.

Front

What is the top view of a 3D figure?

Back

The top view is the view of the figure as seen from above, showing the outline and shape of the figure.

Front

Name a 3D solid figure that has two triangular bases and three rectangular faces.

Back

Triangular prism.

Front

What is the difference between a horizontal and vertical cross-section?

Back

A horizontal cross-section is a slice taken parallel to the base, while a vertical cross-section is a slice taken perpendicular to the base.

Front

What 2D shape results from slicing a cylinder vertically?

Back

Rectangle.

Front

How can you determine the shape of a cross-section from a 3D figure?

Back

By analyzing the orientation and position of the slicing plane relative to the figure.

Front

What is the cross-section of a sphere?

Back

A circle.
