## What type of angle pair is 1 and 4?

alternate exterior angles
In the figure, angles 1 and 4 are alternate exterior angles. Angles that are on opposite sides of the transversal of two other lines. Both are internal. They are equals if the two intersected lines by the transversal are parallel.

What are the 4 angle pairs?

Some of the angle pairs include:

• Complementary angles.
• Supplementary angles.
• Vertical angles.
• Alternate interior angles and alternate exterior angles.
• Corresponding angles.

### What are 4 pairs of vertical angles?

Angles 1 and 2 are a linear pair, so their sum is 180 degrees; therefore, the measure of angle 2 is 180 – 115 = 65 degrees. The measure of angle 4 is 65 degrees because angles 2 and 4 are a pair of vertical angles.

What type of angle pair is 2 and 4?

vertical angles
When two lines intersect at a point, they form two pairs of angles that do not share a side. These pairs are called vertical angles, and they always have the same measure. ∠1 and ∠3 are vertical angles. ∠2 and ∠4 are vertical angles.

#### What are the 5 special angle relationship?

In Geometry, there are five fundamental angle pair relationships: Complementary Angles. Supplementary Angles. Adjacent Angles.

How do you call the longest side of the triangle?

The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. The other two sides are called the opposite and adjacent sides.

## How do you know if two angles are vertical?

When two lines intersect to make an X, angles on opposite sides of the X are called vertical angles. These angles are equal, and here’s the official theorem that tells you so. Vertical angles are congruent: If two angles are vertical angles, then they’re congruent (see the above figure).

What are two parallel lines called?

transversal
In geometry, a transversal is a line that intersects two or more other (often parallel ) lines. In the figure below, line n is a transversal cutting lines l and m .

### How do you call the longest side of the triangle How do you know that it is the longest side?

hypotenuse
The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. The other two sides are called the opposite and adjacent sides.

What is the shortest side of a right triangle?

A right triangle has two shorter sides, or legs, and the longest side, opposite the right angle, which is always called the hypotenuse. The two shorter sides have some other special names, too, based on which acute angle of the triangle you happen to be working with at a particular time.
