exists and is an alternate of .

A pentagon has 540 degrees and five sides. If it is a regular pentagon, then each angle is 108 degrees. An obtuse angle is greater than 90°. A pentagon can be constructed with 2 obtuse angles and 3 non-obtuse (either acute or right) angles.
Example: if it had 3 angles of 90° = 270°. 540° - 270° = 270°, which would be split between 2 angles (each between 90° and 180°).

Can a pentagon have one acute and one obtuse angle?

A 5 sided pentagon has 5 interior angles that add up to 540 degrees. Each interior angle of a regular pentagon measures 108 degrees. An irregular pentagon can have one acute a
