## How do you find the measure of a remote interior angle?

If we extend any of the sides of a triangle, it will form an outside or exterior angle with the triangle. Remote interior angles are angles that don’t share a vertex or corner of a triangle with the exterior angle . The measure of the exterior angle equals the sum of the two remote interior angles .

## How do you find the sides of a polygon with the sum of interior angles?

Finding the Number of Sides of a Polygon You can use the same formula , S = (n − 2) × 180° S = ( n – 2 ) × 180 ° , to find out how many sides n a polygon has, if you know the value of S , the sum of interior angles .

## What is the sum of the sizes of the interior angles of a polygon with 53 sides?

The angles which lie inside a polygon are called the interior angles . The sum of the angles of a polygon with n number of sides is: 180(n−2) 180 ( n − 2 ) .

## How do I find the measure of an angle?

You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent. Two angles whose measures together are 180° are called supplementary e.g. two right angles are supplementary since 90° + 90° = 180°.

## How do you find the measure of an angle?

The best way to measure an angle is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle’s measurement to the nearest degree.

## How do you find the missing angle measure?

To determine to measure of the unknown angle , be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

## What does same side interior angles mean?

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.

## What is mean by remote interior angles?

Definition : An exterior angle is formed by one side of a triangle and the extension of another side. Remote interior angles are the interior angles of a triangle that are not adjacent to a given angle .

## What are the two remote interior angles?

Each interior angle of a triangle has two remote exterior angles and an adjacent interior angle . The remote interior angles are the two angles inside the triangle that do not share a vertex with the exterior angle . The measure of an exterior angle is equal to the sum of the measures of its two remote interior angles .
