parallelogram in general, and a rhombus also, which is a type of parallelogram
Yes, the opposite angles in a regular quadrilateral are equal.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Yes as for example a rhombus is a 4 sided quadrilateral that has 2 equal opposite acute angles and 2 equal opposite obtuse angle and the 4 angles add up to 360 degrees.
Opposite angles of a rhombus are equal and the sum of all four angles is that of any quadrilateral: 360o.
A rhombus is a 4 equal sided quadrilateral and has 2 equal opposite acute angles and 2 equal opposite obtuse angles and they all add up to 360 degrees.

A rhombus is a 4 equal sided quadrilateral with equal opposite acute angles and equal opposite obtuse angles with diagonals that bisect each other at right angles.
you can prove any one of these statements to prove that quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.
Opposite angles of a rhombus are equal and the sum of all four angles is that of any quadrilateral: 360o.
A rhombus is a 4 equal sided quadrilateral and has 2 equal opposite acute angles and 2 equal opposite obtuse angles and they all add up to 360 degrees.
A parallelogram has opposite sides and angles congruent which means of equal measure.
rhombus
Parallogram
A general quadrilateral.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
