So a hexagon can have 5 right-angles, as shown. Sum of Angles = 900'.

What angles do hexagons have?

The sum of the interior angles of a hexagon must equal 720 degrees. Because the hexagon is regular, all of the interior angles will have the same measure. A hexagon has six sides and six interior angles.

Does Pentagon have a right angle?

A regular pentagon has no right angles ( It has interior angles each equal to 108 degrees). An irregular pentagon has at most three right angles, because a fourth would leave 180 degrees to be used for the final angle that is (540 degrees - 360 degrees), which is a straight line.
