Transformations

Front

What is the relationship between the slopes m = 3/4 and m = 4/3?

Back

Neither (the lines are neither parallel nor perpendicular).

Front

What is the midpoint between (10, 9) and (-10, -5)?

Back

(0, 2)

Front

Identify the transformation from C to D: 270° Clockwise Rotation.

Back

270° Clockwise Rotation

Front

Identify the transformation: Translation 5 units left, 1 unit up.

Back

Translation 5 units left, 1 unit up.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way.

Front

Define slope in the context of a line.

Back

Slope is a measure of the steepness of a line, calculated as the rise over run.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

How do you calculate the midpoint of two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is a 90° clockwise rotation?

Back

A 90° clockwise rotation turns a shape 90 degrees to the right around a point.
