## How do you find the measure of each interior angle?

The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

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

To find the measure of the interior angles , we know that the sum of all the angles is 540 degrees (from above) And there are five angles So, the measure of the interior angle of a regular pentagon is 108 degrees. To find the measure of the central angle of a regular pentagon , make a circle in the middle

## 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 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°.

## What is the measure of each interior angle of a regular decagon?

A regular decagon has 10 equal- length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° .

## What is the formula for finding the area of a pentagon?

Using a Formula . Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don’t know the perimeter, calculate it from the side length: p = 5s, where s is the side length.

## What is an interior angle of a triangle?

60° (for equilateral)

540°

## 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 .

180°

900°

## 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 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 .
