When a transversal crosses two parallel lines, angles that are on opposite sides of the transversal but outside the lines are called these.
Alternate exterior angles
If two triangles are similar, the ratios of their corresponding sides are set up as this type of equation.
Proportion
This trigonometric ratio is defined as the length of the adjacent side divided by the length of the hypotenuse.
