No, a parallelogram does not have any right angles by definition. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Right angles are angles that measure exactly 90 degrees, which are not present in a parallelogram unless it is a special case like a rectangle or a square.
Not always. A parallelogram only has to have two equal parallel sides and its angles does not have to be 90°. Only two types of parallelogram, the rectangle and the square, have four right angles.
