The Interior Angles of a Pentagon add up to 540°The General RuleEach time we add a side (triangle to quadrilateral, then to pentagon, and so on), we add another 180° to the total:If it is a Regular Polygon (all sides are equal, all angles are equal) ShapeSidesSum of Interior ...
of one interior angle, we would know the measure of all interior angles. The formula for finding the measure of each interior angle is again determined by the number of sides of the polygon… EXAMPLE # 1 : What are the measures of the interior angles of a regular polygon with 5 sides ...
Do the angles of a pentagon add up to 360? The five interior angles in a pentagon always add up to 540 degrees. This is true whether the pentagon is regular or irregular. Does a pentagon have 5 right angles? A pentagon does not have 5 right angles. The sum of the 5 angles in a ...
Example 2.The exterior angles of a regular pentagon are y, 2y, 3y, 4y, and 8y. What is the size of the smallest interior angle of this pentagon? Solution: The sum of the exterior angles of a regular polygon is 360°. Therefore y + 2y + 3y + 4y + 8y = 360° ...

Types of Pentagrams Like any otherpolygon, pentagrams can also be classified into two different types. There are two types of pentagrams - regular and irregular. Regular Pentagrams A regular pentagram consists of a regular pentagon in its center, and 5 congruentisosceles trianglesforming the 5 ...
The diagram below shows how this can be used on a pentagon (a five-sided polygon). Interior angles of a pentagon My own image The Interior Angle Sum of Further Polygons We can see in the pentagon diagram that a pentagon is split into three internal triangles, so it must have an interio...
