FA 2 Scale Factor

Front

What is the definition of Scale Factor?

Back

Scale Factor is the number you multiply by the sides of a shape to create a similar figure.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What is the formula for calculating slope?

Back

The formula for slope (m) is m = \frac{y_2 - y_1}{x_2 - x_1}.

Front

What is a scaled copy?

Back

A scaled copy is a shape that is the same shape but different in size compared to the original.

Front

Which of the following is NOT true about slope: y/x, can be positive or negative, x/y?

Back

x/y is NOT true about slope.

Front

Back

This represents the ratio of the vertical change (rise) to the horizontal change (run) between points A and C.

Front

Are triangles drawn along a line similar if they have the same angles?

Back

Yes, triangles are similar if they have the same angles.

Front

What is the relationship between scale factor and similar figures?

Back

The scale factor determines how much larger or smaller a similar figure is compared to the original figure.

Front

If a triangle has a scale factor of 2, what happens to its area?

Back

The area of the triangle increases by a factor of 2^2 = 4.
