Variables are in proportion if they have a constant multiplicative relationship.

A ratio shows the relative sizes of 2 or more values and allows you to compare a part with another part in a whole.

Bearings

A scale factor is the multiplier between similar shapes that describes how large one shape is compared to the other.

A degree of accuracy shows how precise a number or measurement is.

A bearing is an angle measured in degrees from North in the clockwise direction and written with three figures.

A transversal is a line, line segment, or ray that intersects through two or more lines at distinct (different) points.

Corresponding angles are a pair of angles at different vertices on the same side of a transversal in equivalent positions.

Alternate angles are a pair of angles, both between or both outside two line segments, that are on opposite sides of the transversal that cuts them.

Co-interior angles are on the same side of the transversal line and in between the two other lines.
