A pentagon has no right angles at all. Each pentagon has 5 equal sides, which results in internal angles of 108° each. A right angle must be 90°, which is too small to be part of a pentagon.
None in a regular pentagon but it's quite possible to have right angles in an irregular pentagon.
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.
If you wan't to show that a pentagon has no right angles, then don't put any right angle signs in the figure.
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.
