Back

twice

Front

All angles in similar figures are congruent. True or False?

Back

True

Front

If the ratio of the radii of two circles is 3:4, what is the ratio of their areas?

Back

9:16

Front

What does 'three-dimensional' mean?

Back

having the dimensions of height, width, and depth

Front

Determine the relationship of the figures: Congruent, Not Congruent, or Similar?

Back

Congruent

Front

What is the formula for the volume of a cylinder?

Back

V = πr²h

Front

What is the relationship between the surface area and volume of similar 3D figures?

Back

The ratio of surface areas is the square of the ratio of corresponding lengths; the ratio of volumes is the cube of the ratio of corresponding lengths.

Front

What is a prism?

Back

Front

What is the formula for the surface area of a sphere?

Back

SA = 4πr²

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size; similar figures have the same shape but different sizes.
