None normally as in the form of a regular 5 sided pentagon.
a pentagon has 5 angles. In a regular pentagon, there are no right angles. Each angle is 72 degrees. In a irregular pentagon, there may be right angles...not sure how many..depends on how you draw it
A pentagon can have:none (regular or irregular pentagon)one, two or three right angles (irregular pentagon).
A regular pentagon has no right angles. An irregular pentagon could have no more than two right angles
A pentagon can have anywhere from none to three right angles. For a pentagon to have any right angles however, it has to be uneven, because the sum of all interior angles of a pentagon always equals 540 degrees.
A two dimensional regular pentagon does not contain any right angles. A pentagonal prism, however, contains up to 10 right angles.
None, since there are no right angles in a pentagon. The angles are 360/5 = 72o
A pentagon has 5 sides.A regular pentagon has no right angles (5 interior angles each 108 degrees).An irregular pentagon can have at most 3 right angles, because a 4th would leave 180 degrees to be used for the final angle (540-360), which is a straight line.

None.
A pentagon need not have any right angles at all, and in fact, a regular pentagon never has any.A pentagon that's not regular can have any number of right angles less than five.
The square has four right angles. The pentagon has two right angles.
