3.1.3: Reflection and Practice

Front

What is the cross section of a square pyramid when sliced parallel to its base?

Back

The cross section will look like a square.

Front

What happens to the size of the cross sections when slicing a square pyramid at different heights?

Back

The squares get smaller as you slice higher on the pyramid.

Front

What is a proportional relationship in a graph?

Back

A proportional relationship is represented by a straight line that passes through the origin.

Front

Why is a graph not considered a proportional relationship if it does not pass through the origin?

Back

Because proportional relationships must start from the origin (0,0) and maintain a constant ratio.

Front

What does it mean for mathematicians to attend to precision?

Back

It means they focus on accuracy and clarity in calculations and representations.

Front

What is the definition of a cross section in geometry?

Back

A cross section is the intersection of a solid and a plane.

Front

How does the shape of a cross section change when slicing a cone horizontally?

Back

The cross section will be a circle.

Front

What is the relationship between the height of a pyramid and the size of its cross sections?

Back

As the height increases, the size of the cross sections decreases.
