What Are Alternate Interior Angles And Alternate Exterior Angles

Lie on the alternate sides of the transversal.

What are alternate interior angles and alternate exterior angles. Similar to before angles 1 2 7 and 8 are exterior angles. If two parallel lines are cut by a transversal then the alternate angles are equal. Are exterior to the lines.

Alternate exterior angles are created in the space outside the parallel lines on alternating sides. Rs is the transversal line that cuts ef at l and gh at m. When two lines are crossed by another line called the transversal 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.

From the above given figure 1 2 7 8 are the alternate exterior angles. Also like with interior angles the above exterior angles are equal when a transversal line crosses 2 parallel lines. Interior angles are created in the space inside the parallel lines.

Alternate exterior angles are those angles that. Which means they add up to 180 degrees. If lines are parallel then same side interior angles are supplementary and same side exterior angles are supplementary.

Alternate angles are shaped by the two parallel lines crossed by a transversal. Angles 2 and 7 are alternate and angles 1 and 8 are alternate. When a transversal intersects two parallel lines alternate exterior angles formed are always equal.

Use this info to solve for. Alternate interior angles lie between the lines cut by the transversal. If lines are parallel then corresponding angles are congruent alternate interior angles are congruent and alternate exterior angles are congruent.
