Alternate Exterior Angles Math Definition

Alternate exterior angles are created where a each pair of these angles are outside the parallel lines and on opposite sides of the transversal.

Alternate exterior angles math definition. Alternate exterior angles definition of alternate exterior angles when two lines are cut by another line t r a n s v e r s a l the pairs of angles formed outside the two lines and on the opposite of the transversal are called alternate exterior angles. To help you remember. If the two lines are parallel then the theorem tells you that the alternate exterior. Formally alternate exterior angles are defined as two exterior angles on opposite sides of a transversal which lie on different parallel lines.

The angles formed by the transversal and the lines that are on opposite sides of the transversal but on the outside of the two lines are called alternate exterior angles. Two exterior angles which lie on two different lines cut by a transversal and are placed on the opposite sides of the transversal are called alternate exterior angles. Alternate exterior angles lie outside the lines cut by the transversal. When two lines are crossed by another line called the transversal.

When two lines are crossed by another line the transversal a pair of angles. A line that crosses two or more other lines is called a transversal. Alternate interior angles create a z. Alternate exterior angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.

Try thisdrag an orange dot at a or b. On the outer side of those two lines. Alternate exterior angles in the drawing below angles 1 and 8 are alternate exterior angles as are angles 2 and 7. Alternate exterior angles are congruent.

Alternate exterior angles are angles that are on opposite sides of the transversal and outside the two lines. We can observe here that a and b are alternate exterior angles as both lie in the exterior of lines p and q and are placed on the opposite sides of the transversal. Alternate exterior angles definition alternate exterior angles are created when three lines intersect. But on opposite sides of the transversal.

More about alternate exterior angles. Alternate exterior angles are supplementary to the adjacent angles. Alternate interior angles are used to prove triangles are congruent by sas asa aas. Often two of the lines will be parallel setting up some interesting angles with the transversal.

Play with it below try dragging the points. Definition of alternate exterior angles when two lines are crossed by a transversal a third line that crosses both lines a number of different pairs of angles are formed. The angle pairs are on alternate sides of the transversal and they are on the exterior of the two crossed lines.
