A parallelogram.
square
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.
Base angles are equal and non-parallel sides are equal in length.
Pentagon
A rhombus.
A rhombus has 4 sides of equal length, opposing parallel sides, and no right angles
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, and opposite angles that are equal. Two ways to describe a parallelogram could be as a shape with opposite sides that are both parallel and equal in length, or as a shape with opposite angles that are equal.
A polygon with four sides that has equal opposite sides parallel and four equal angles is called a rectangle. In a rectangle, opposite sides are both equal in length and parallel, while each of the four angles measures 90 degrees. If all four sides are also equal in length, the rectangle becomes a square.
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
No triangle has two parallel sides.None but it does have 2 sides of equal length and 2 angles of equal measure.
Rhombus ; Internal 2 acute and two obtuse angles; four sides of equal length, opposite sides are parallel. Rectangle ; Internal angles are all 90 degrees(right angles), opposite sides of equal length and parallel. Adjacent sides are of different length.
