# What is the definition of same side exterior angles

## What is the definition of same side interior angles?

Same side interior angles are

**two angles that are on the same side of the transversal and on the interior of (between) the two lines**. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.## How do you find same side exterior angles?

## Are the same side exterior angles always congruent?

**All angles that are either exterior angles, interior angles, alternate angles or corresponding angles are all congruent**.

## What is the definition of exterior of an angle?

Definition of exterior angle 1 : the angle between a side of a polygon and an extended adjacent side. 2 : an angle formed by a transversal as it cuts one of two lines and situated on the outside of the line.

## How many pairs of same side exterior angles are there?

Each pair of exterior angles are outside the parallel lines and on the same side of the transversal. There are thus

**two pairs**of these angles.## What is the difference between same side interior angles and same side exterior angles?

The same side interior angles are the angles inside the parallel lines on the same side of the transversal and the same side exterior angles are the angles outside the parallel lines on the same side of the transversal.

## Are exterior angles equal?

What is the Exterior Angle Theorem? The exterior angle theorem states that

**the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle**. The remote interior angles are also called opposite interior angles.## What does exterior mean in maths?

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

## How do you write an exterior angle?

Exterior angle =

**sum of two opposite non-adjacent interior angles**. Simplify. Subtract 120Â° from both sides.## What is exterior angle example?

**An exterior angle of a triangle is equal to the sum of the two opposite interior angles**. Example: Find the values of x and y in the following triangle. y + 92Â° = 180Â° (interior angle + adjacent exterior angle = 180Â°.)

## What is exterior angle property class 8?

CBSE NCERT Notes Class 8 Maths Understanding Quadrilaterals.

**For a polygon, the sum of the exterior angles is always 360Â°regardless of the number of sides of the polygon**. The sum of angles in a linear pair is always 180Â°.## What is exterior angle property class 9?

Exterior angle property –

**Exterior angle is equal to sum of interior**.## What is the formula for the exterior angle theorem?

The exterior angle theorem states that

**the exterior angle formed when you extend the side of a triangle is equal to the sum of its non-adjacent angles**. The theorem tells us that the measure of angle D is equal to the sum of angles A and B.## What do the exterior angles of a triangle equal?

The measure of an exterior angle of a triangle is equal to

**the sum of the measures of the two non-adjacent interior angles of the triangle**.## How many degrees is a triangle?

180Â°Learn the formal proof that shows the measures of interior angles of a triangle sum to 180Â°.

## What is the name of the exterior angle in the figure?

Answer. 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 180Â°. They are “

**Supplementary Angles**“.## What is the sum of two exterior angles on the same side of the transversal?

Two angles that are exterior to the parallel lines and on the same side of the transversal line are called same-side exterior angles. The theorem states that same-side exterior angles are supplementary, meaning that they have a sum of 180 degrees.

## Why does the sum of exterior angles equal 360?

Summed, the exterior angles equal 360 degreEs. A special rule exists for regular polygons:

**because they are equiangular, the exterior angles are also congruent**, so the measure of any given exterior angle is 360/n degrees.
