What is the sum of the interior angles of a polygon having 5 sides?
Regular pentagons where all the sides and angles are the same will have a sum of interior angles of 540 degrees.
What is the sum of exterior angle of a pentagon?
This means: Sum of exterior angles = 180n – 180(n-2) = 180n – 180n + 360. Hence, the sum of exterior angles of a pentagon equals 360°.
What is the sum of sides of a regular pentagon?

What are the interior and exterior angles of a pentagon?
A regular pentagon has the following properties: Interior angles that measure 108° Exterior angles that measure 72°
What is the sum of exterior and interior angle of a polygon?
The angles are formed by one side of the polygon and extension of the other side. The sum of an adjacent interior angle and exterior angle for any polygon is equal to 180 degrees since they form a linear pair. Also, the sum of exterior angles of a polygon is always equal to 360 degrees.
What is the sum of exterior angles of a pentagon?
The exteriors angles of a pentagon are (m + 5)°, (2m + 3)°, (3m + 2)°, (4m + 1)° and (5m + 4)° respectively. Find the measure of each angle. Hints: The sum of all exterior angles of a polygon is 360°.
What is the exterior angle of a regular pentagon?
Answer: The measure of each exterior angle of a regular pentagon is 72° A regular pentagon has all angles of the same measure and all sides of the same length.
What is sum of exterior angles of a pentagon?
What is the interior sum of a triangle?
Learn the formal proof that shows the measures of interior angles of a triangle sum to 180°.
What is the sum of interior and exterior angles?
Exterior Angles
The sum of an adjacent interior angle and exterior angle for any polygon is equal to 180 degrees since they form a linear pair.
How do you find sum of interior angles?
The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

How many angles are in a pentagon?
five angles
A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle. The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees.
What is the sum of hexagon?
For example a hexagon has 6 sides, so (n-2) is 4, and the internal angles add up to 180° × 4 = 720°.
What is the sum of parallelogram?
360 degrees
The opposite interior angles are equal. The angles on the same side of the transversal are supplementary, that means they add up to 180 degrees. Hence, the sum of the interior angles of a parallelogram is 360 degrees.
