When two lines are crossed by another line (which is called the Transversal), the pairs of angles: • on opposite sides of the transversal. • but outside the two lines. are called Alternate Exterior Angles. When the two lines are parallel Alternate Exterior Angles are equal.

Anyone in the mathematics field that works with coordinates would use these types of angles

Now 2πr is the circumference of each circle. And each circumference is an "arc" that subtends four right angles at the center. Therefore, the same ratio of arc length to radius determines a unique central angle that the arcs subtend.

Anyone that works in the car industry/ makes wheels would use this to make sure that their wheels are as round as possible

Associative Property of Addition and Multiplication

kinnesl057 — 2015-09-16 01:40:13 UTC

Parentheses show the association and the operations in the parentheses are performed first. Notice that the order of the numbers does not change – only the grouping. The associative property becomes important because it allows the mathematician, you, to add or multiply numbers with ease.

A math teacher would teach this to students when learning multiplication/ division because it is easy for them to explain and easy for students to understand
