What is a scale model?

Back

A scale model is a representation of an object that maintains accurate relationships between its dimensions, often used to visualize larger structures in a smaller size.

Front

How do you calculate the actual size from a scale model?

Back

To find the actual size, multiply the size of the model by the scale factor. For example, if the scale is 5 in:25 ft, the scale factor is 5/25 or 1/5.

Front

If a model window is 1.5 in wide, how wide is the actual window if the scale is 5 in:25 ft?

Back

The actual window is 7.5 ft wide.

Front

What is a scale factor?

Back

A scale factor is a ratio that compares the dimensions of a model to the dimensions of the actual object.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and does not rise or fall.

Front

How do you find the slope between two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through the points (6, -8) and (10, -8)?

Back

The slope is 0.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines on opposite sides of a transversal.
