Pentagon Interior Angles
Its interior angles add up to 3 180 540 and when it is regular all angles the same then each angle is 540 5 108 exercise.
Pentagon interior angles. A pentagon has 5 sides and can be made from three triangles so you know what. In the case of a regular pentagon the interior angle is equal to 108 and the exterior angle is equal to 72. Sum of interior angles of a three sided polygon can be calculated using the formula as.
Interior angle sum of a pentagon 3 x 180 540 if the polygon. The pentagon 5 sided shape above can be split into 3 triangles. Polygons are also classified as convex and concave polygons based on whether the interior angles are pointing inwards or outwards.
The sum of the internal angles in a simple pentagon is 540. A pentagon has 5 sides and when divided contains 3 triangles. To find the sum of the interior angles you multiply 3 by 180.
The sum of the interior angles of a pentagon is 540 degrees. All sides are the same length congruent and all interior angles are the same size congruent. The properties of regular pentagons.
A self intersecting regular pentagon or star pentagon is called a pentagram. Regular pentagons where all the sides and angles are the same will have a sum of interior angles of 540 degrees. Sum of interior angles p 2 180 60 40 x 83 3 2 180 183 x 180 x 180 183.
And there are five angles. Weird shaped pentagons where one side is super long will also have a sum of interior. Look at the image opposite.
