8th Grade GA Milestones Review

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

How can you determine if a relation is a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a 90° clockwise rotation?

Back

A transformation that turns a figure 90 degrees to the right around a point.

Front

What is the relationship between angles ∠ABD and ∠DBC if ∠ABD is 67°?

Back

If ∠ABD is 67°, then ∠DBC is 23°.

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

How do you find the slope of a line given in standard form?

Back

Rearrange the equation to slope-intercept form (y = mx + b) to identify the slope (m).

Front

What is the slope of the line represented by the equation 2x - y = 9?

Back

The slope is 2.

Front

What is a transformation in geometry?

Back

A change in the position, size, or shape of a figure.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips it over a line.

Front

What are alternate interior angles?

Back

Angles that lie between two parallel lines and on opposite sides of a transversal.
