Front

Definition of a midpoint in geometry.

Back

The midpoint is the point that divides a line segment into two equal parts.

Front

How to calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Back

180 degrees.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the definition of parallel lines?

Back

Lines that never intersect and have the same slope.
