Geometry Module 3 Vocab Part 2

Front

When two lines are crossed by another line, the pairs of angles on opposite sides of the transversal but inside the two lines.

Back

Alternate Interior Angles

Front

Noncoplanar lines that do not intersect.

Back

Skew

Front

When two lines are crossed by another line, the angles in matching corners.

Back

Corresponding Angles

Front

A line that intersects two or more lines in a plane at different points.

Back

Transversal

Front

The ratio of the change in the y-coordinates (rise) to the corresponding change in the x-coordinates (run) as you move from one point to another along a line. The steepness of a line.

Back

Slope

Front

Coplanar lines that do not intersect.

Back

Parallel Lines

Front

When two lines are crossed by another line, the pairs of angles on opposite sides of the transversal but outside the two lines.

Back

Alternate Exterior Angles

Front

When two lines are crossed by another line, the pairs of angles on one side of the transversal but inside the two lines.

Back

Consecutive Interior Angles

Front

A way of writing two conditionals at once: both a conditional and its converse.

Back

Biconditional Statements

Front

An example that contradicts the conjecture showing that the conjecture is not always true.
