A rectangle, possibly a square. Can you see why a parallelogram must be a rectangle if any one of its angles is right?
yes 4 right angles
Except for rectangles, no parallelogram has right angles.
Yes.
No, all angles are right angles
NOPE!! a cylinder has no obtuse angles nor acute or right
No When a right cylinder is viewed at right angle to its axis the projected form can be a square or a rectangle, which have 4 right angles. The same applies if the cylinder is cut through on any plane parallel to its axis.
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
Circle, cone, cylinder, sphere and equilateral triangle for example.
a circle
Yes. Rectangles have four right angles.
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.
Strictly, if it has a circular base, it is a circular cylinder. Otherwise, it could have an oval base. If the long axis is at right angles (perpendicular) to the plane of the base, then it is a right circular cylinder.
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.
