A regular hexagon as no right angles. An irregular hexagon could have from none to as many as five right angles.
a tetrahedron has 3 Right angles
the answer is 5 each tip of the star is a acute angle and each angle on the inside of the star is an obtuse angle. there are 5 obtuse angles and no right angles.
10 angles
4 right angles, no other angles.
Oh, dude, a star has like, five points, so you'd think it has five right angles, right? But, like, actually, each point of a star is made up of two line segments, so it has ten right angles in total. Math can be pretty sneaky like that, huh?
