a square which is a subset of rectangles
No. A quadrilateral is a any closed polygon with four sides. A rectangle is a quadrilateral with four right angles and congruent opposing sides. Therefore, all rectangles are quadrilaterals, but not all quadrilaterals are rectangles.
Yes, rectangles are a special case of parallelogram, with four right angles.
Yes. A square is both a rhombus and a rectangle. A rectangles is a figure with four right angles, and all squares do indeed have four right angles. A rhombus has four equal sides, and all squares meet this requirement.
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.
yes.
A rectangle. A square is a form of rectangle. (All squares are rectangles, but not all rectangles are squares.) ___________ |__________|
No, all four angles with in a rectangle are right angles.
Yes. Rectangles have four right angles.
No. Although squares are always rectangles, rectangles are not always squares. A square has four sides of equal length and four right angles. Rectangles must only have four right angles.
Rectangles are parallelograms with four 90o corners. These are known as right angles, and indeed, 'rectangle' comes from latin, 'rectus' meaning 'right' and 'angulus' meaning 'angle'. A rectangle is considered a square if the sides all have equal length. Because all squares have four right angled corners, they are all, by definition, rectangles.
A quadrilateral with four right angles is a rectangle. If all its sides are the same then it is a square.
Rectangles have four right angles so, yes, all squares are rectangles because they also have four right-angled corners. However, rectangles can have sides of any length, as long as the opposite sides are of equal length, whereas a square has all four sides of equal length. A more technical reply could be that a rectangle has two pairs of congruent and parallel sides, which all squares have.

No. A quadrilateral is a any closed polygon with four sides. A rectangle is a quadrilateral with four right angles and congruent opposing sides. Therefore, all rectangles are quadrilaterals, but not all quadrilaterals are rectangles.
If the all four angles in a parallelogram are right angles, then it becomes a rectangle.
