Such a figure is called a square. Actually only one right angle is enough to force the
the other angles to be right, and if three sides are equal, that forces all sides in
such a figure to be equal.
Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
a parallelogram with four right angles with sides different in length and width is That would be a rectangle. - HistoryDork
They can be, but they do not have to be. A rectangle has 4 sides and 4 right angles. Which means a square, which is a type of rectangle, would have 4 of the same length sides.
A rectangle.
A Rectangle.
A parallelogram with equal angles and two pairs of sides of different lengths is a Rectangle. The rectangle is a special case of the parallelogram where the angles are all equal at 90°.
A rectangle has 4 sides not the same length and 4 right angles.

A rectangle
A rectangle with all sides the same length is referred to as a "square". It's not necessary to specify that it has "4 right angles". If it's a "rectangle", then we already know that.
They can be, but they do not have to be. A rectangle has 4 sides and 4 right angles. Which means a square, which is a type of rectangle, would have 4 of the same length sides.
The right answer is a rectangle.
It is a rectangle.
a rectangle
It is a rectangle. Just picture it. 4 right angles and 2 sides that are the same length.
It is a RECTANGLE
rectangle
A shape that has four right angles is a rectangle. If all four sides are equal in length, then it is a square.
