1 Expert Answer. Vertical angles are a pair of nonadjacent angles, ∠1 and ∠2, formed by two intersecting lines. A linear pair is two adjacent angles, ∠3 and ∠4, formed by opposite rays. Thus, the vertical angles are not also a linear pair.

## Do vertical angles make a straight line?

The two angles are opposite of each other. Next, decide if the angles are adjacent or vertical. The two angles are vertical angles. It is adjacent, because together they form a straight line.

## What do linear pairs and vertical angles have in common?

The difference between vertical angles and linear pairs of angles is that linear pairs of angles has two adjacent angles whose noncommon sides form opposite sides and vertical angles have two adjacent angles that have common sides that and they have a common vertex.

## What is the difference between linear and vertical angles?

A Linear Pair is two adjacent angles whose non-common sides form opposite rays. ∠1 and ∠2 form a linear pair. Vertical Angles are two angles whose sides form two pairs of opposite rays (straight lines). Vertical angles are located across from one another in the corners of the “X” formed by the two straight lines.

## Are vertical angles the same?

When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal.

## What are alternate angles simple definition?

Alternate angles are angles that are in opposite positions relative to a transversal intersecting two lines. Examples. If the alternate angles are between the two lines intersected by the transversal, they are called alternate interior angles.

## What is the sum of alternate interior angles?

These angles are congruent. The Sum of the angles formed on the same side of the transversal which are inside the two parallel lines is always equal to 180°. In the case of non – parallel lines, alternate interior angles don’t have any specific properties.
