Are the angles in a quadrilateral opposite or adjacent?
- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.
What quadrilateral has no equal angles and its opposite sides are parallell?
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
Can a quadrilateral be a rectangle if the sides are not equal?
Yes, but there must be two pairs of opposite sides that are equal.Yes, but there must be two pairs of opposite sides that are equal.Yes, but there must be two pairs of opposite sides that are equal.Yes, but there must be two pairs of opposite sides that are equal.
What is a quadrilateral with four right angles and two sets of parallel opposite sides that are equal?
a square

Two pairs of equal length sides but opposite sides not equal length?
This is a quadrilateral. It could be a symmetric trapezium /

What ia a parallelogram?
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.

Which quadrilaterals are opposite angles always congruent?
(1) Parallelogram A parallelogram is a quadrilateral with two sets of parallel sides. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal.(2) SquareA square is a regular quadrilateral. This means that is has four equal sides and four equal angles.(3) RhombusA rhombus is a quadrilateral whose four sides all have the same length. Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular.(4) RectangleA rectangle normally refers to a quadrilateral with four right angles.ParallelogramSquareRhombus
Can a quadrilateral be a parallelogram?
Yes, because a square is a parallelogram
How do you define a Parallelogram?
A parallelogram is a 4 sided quadrilateral that has two pairs of opposite parallel sides and two equal opposite acute angles and two equal opposite obtuse angles whereas the 4 angles add up to 360 degrees.
