Alternate Exterior Lines

A transversal is a line like the red one below that intersects two other lines.

Alternate exterior lines. Here are lines T R and I P which would definitely cross somewhere in the distance. You can create a customized shareable link at bottom that will remember the exact state of the app--which angles are selected and where the points are so that you can share your it with others. The alternate exterior angles are the opposing pair of exterior angles formed by the transversal and the two lines.

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. Exterior angles are also created by a transversal line crossing 2 straight lines. Alternate exterior angles are angles that are on opposite sides of the transversal and outside the two lines.

If the two lines are parallel then the theorem tells you that the alternate exterior. Parallel and Perpendicular Lines Transversals Alternate Interior Angles Alternate Exterior Angles - YouTube. Alternate exterior angles are created in the space outside the parallel lines on alternating sides.

In the diagram above a and d makes a pair of alternate exterior angles and b and c makes another pair of alternate exterior angles. If just one of our two pairs of alternate exterior angles are equal then the two lines are parallel because of the Alternate Exterior Angle Converse Theorem which says. A transversal is a line that intersects two or more coplanar lines each at a different point.

Angles 2 and 7 are ALTERNATE and angles 1 and 8 are ALTERNATE. The transversal line is defined as A line which intersects two or more lines at distinct points. Interior angles Exterior Angles Alternate Interior and Alternate Exterior Angles.

If two lines in. Depending on the nature of the lines the angles will have some characteristics. Pairs of alternate exterior.
