A triangle can have 1 or less.
A 4-sided polygon can have zero, 1, 2, or 4.
A 5-sided polygon can have 3 or less.
The possibilities always depend on the number of sides in the polygon,
but the polygon is never required to have anyright angles.
An irregular pentagon is a polygon that has five sides and two right angles. A regular polygon on the other hand does not have right angles.
a polygon with 5 sides and 2 right angles is a pentagon
Any polygon can have at least one right angled - for example a right angled triangle. An example of an irregular polygon with only right angles is a rectangle.
Any polygon with 4 or more sides can have only two right angles.
regular polygon\
A triangle
All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.
a polygon with 4 right angles and 4 sides of the same length
no, because a polygon with four right angles is a rectangle
3 right angles
No REGULAR polygon can have three right angles in it. Any polygon with five or more sides CAN have three right angles, as long as it's not regular.
