*EOC review Flashcard #1 Geometry*

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

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 determine if two lines represented by equations are parallel or perpendicular?

Back

Convert the equations to slope-intercept form (y = mx + b) and compare the slopes.

What is the midpoint formula?

Back

The midpoint M between two points (x1, y1) and (x2, y2) is given by M = (\frac{x1 + x2}{2}, \frac{y1 + y2}{2}).

Front

Find the midpoint between the points (-4, 4) and (-2, 2).

Back

The midpoint is (-3, 3).

How can you identify parallel lines from their equations?

Back

If two lines have the same slope in slope-intercept form, they are parallel.
