What is alternate exterior angles Converse?

Converse of the Alternate Exterior Angles Theorem: If two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel.

What is alternate exterior angle with example?

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. In this example, these are two pairs of Alternate Exterior Angles: a and h.

What do exterior angles look like?

The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. When we add up the Interior Angle and Exterior Angle we get a straight line 180°.

How do you calculate alternate exterior?

To find exterior angles, look in the space above and below the crossed lines. To find alternate exterior angles, look at that outside space for each crossed line, on different sides of the transversal. We hope you said ∠1 , ∠2 , ∠7 , and ∠8 are the exterior angles.

What is alternate angle test?

The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .

What is converse alternate interior angles theorem?

If two lines are cut by a transversal so that the alternate interior angles are congruent, then the lines are parallel.

What is a vertical angle in geometry?

Vertical angles are angles opposite each other where two lines cross.

Why are alternate exterior angles equal?

Alternating exterior angles are equal when the transversal crosses two parallel lines. Therefore, equate the two angles. The two angles are not congruent. This implies that the two lines intersected by the transversal are not parallel.

What is exterior geometry?

The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior Angle and Exterior Angle we get a straight line 180°.

What does exterior mean in math?

The angle between any side of a shape, and a line extended from the next side.
