# How Do I Find A Pair Of Exterior Angles?

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.

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 ∠ 1, ∠2 ∠ 2, ∠7 ∠ 7, and ∠8 ∠ 8 are the exterior angles.

## Classify Angle Pairs as Corresponding, Alternate Interior, Alternate Exterior, Consecutive Interior

### What is pairs of exterior angles?

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.

### What is the formula for alternate exterior angles?

Two alternating exterior angles are given as (2x + 10) ° and (x + 5) °. Check whether the angles are congruent. Alternating exterior angles are equal when the transversal crosses two parallel lines. Therefore, equate the two angles.

### How do you know if an angle is alternate exterior angles?

One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles. Alternate exterior angles are equal to one another. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.

### How to find the exterior angles of a building?

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 ∠ 1, ∠2 ∠ 2, ∠7 ∠ 7, and ∠8 ∠ 8 are the exterior angles.

### When do the four alternate exterior angles appear?

The four exterior angles: Alternate exterior angles are pairs that appear outside the crossed lines and on different lines: When two lines are parallel, the transversal creates congruent alternate exterior angles. The theorem says:

### How to find the alternate interior angles of a line?

Step 1: x is a supplement of 65°. Therefore, x + 65° =180° ⇒ x = 180° – 65° = 115° When a line intersects a pair of parallel lines alternate interior angles are formed. Alternate interior angles are equal to each other. One way to find the alternate interior angles is to draw a zigzag line on the diagram.

### Is the exterior angle of a triangle an interior angle?

It can be tempting to think that any outside angle that touches a triangle is an exterior angle. Make sure to remember that an exterior angle must form a linear pair with an interior angle. It needs to share a side with an interior angle and the two together must form a straight line. Welcome to Kate's Math Lessons!
