Yes, each pair of two opposite sides is parallel and equal in length. This is necessary to achieve the symmetry of the angles.
The answer is any rectangle that is not a square: such a rectangle has two lines of symmetry, whereas a square has four.
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.
Whether or not the opposing angles of a trapezoid (UK trapezium) are equal depends on the axis of symmetry. A trapezoid (trapezium) can be defined as a quadrilateral with one pair of opposite sides parallel. It is not a parallelogram because only one pair of sides is parallel. It is called a regular trapezoid if the sides that aren't parallel are equal in length and both angles coming from a parallel side are equal
Base angles are equal and non-parallel sides are equal in length.
A rhombus has 4 sides of equal length, opposing parallel sides, and no right angles
opposite sides are equal in length and parallel opposite angles are equal adjacent angles add up to 180 degrees no lines of symmetry base x vertical height = area sum of internal angles = 360 degrees sum of external angles = 360 degrees
square and rectangles are technicality squares
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
Opposite sides are equal in length. Opposite angles are equal. It is also known as a parallelogram.
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.
A rectangle perhaps?
This is a parallelogram, opposite sides are of equal length and opposite angles are equal in size.
its a rhombus
