In a circle no, in a square yes.
No, if it has right angles it is a special case, such as rectangle, but in general it does not have to have any right angles
The exterior angles of any polygon always add up to 360 degrees because there are 360 degrees in a full rotation.
a circle
Yes. Rectangles have four right angles.
No, a cylinder does not have any right angles because it has two circles and a tube comprising it so as they do not have any right angles, the cylinder will not either.
A shape with 4 right angles would be a square or rectangle. A trapezoid does not have any right angles..
Yes a square always has 4 right angles but a rhombus never has any right angles.
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!
It can.Quadrilateral means "four sides", and squares and rectangles do have right angles. Rhombuses are quadrilaterals, but do not have right angles.
A rhombus normally has no right angles (at the vertices). If a rhombus has right angles (at the vertices), it is called a square. The diagonals of a rhombus meet at right angles.
No a sphere doesn't even have any angles
