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 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.
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.
The square has four right angles. The pentagon has two right angles.
