Opposite sides are parallel; opposite sides are equal; opposite angles are equal.

### What is a quadrilateral with opposite sides and opposite angles?

The practical answer is a parallelogram, which has two sets of parallel opposite sides and two sets of equal opposite angles. This includes rhombi, rectangles, and squares. A trapezoid (trapezium) has one set of parallel opposite sides that are not equal, but may have non-parallel opposite sides equal in length (isosceles trapezoid).

### What is true about both a rhombus and a square?

-- Opposite sides are parallel. -- Opposite sides are equal. -- All four sides are equal. -- Adjacent sides are equal. -- Adjacent angles are supplementary. -- Opposite angles are equal. -- Diagonals are perpendicular. -- Interior angles sum to two straight angles. -- Exterior angles sum to two straight angles.

### Is all quadrilaterals are parallelograms truth?

opposite sides are parallel opposite sides congruent opposite angles are equal opposite lines parallel 1 pair opp. lines parallel and congruent

### Is a rhombus a square explain why?

They are both 4 equal sided quadrilaterals with opposite parallel sides but a square has 4 equal interior angles of 90 degrees whereas a rhombus has 2 equal opposite acute angles and 2 equal opposite obtuse angles.

### Why are the opposite angles in a parellelogram equal?

Because they are angles that are subtended by pairs of sides that are parallel to each other. There are several ways of proving the angles are equal.

### What plane has opposite sides equal and parallel and no angles equal to 90 degrees?

A rhombus or a parallelogram

### Which quadrilateral has opposite sides that are not parallel and have angles that are not equal?

All quadrilaterals apart from rectangles. Even parallelograms have adjacent angles that are not equal.

### What has a opposite sides equal and parallel and 4 right angles?

It is a square or a rectangle

### What has 4 equal sides and its opposite sides are parallel and it has no right angles what is it?

a parallogram

### What does parallelogram mean in math?

A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal

### What is a four sided figure with opposite sides equal and parallel and opposite angles equal?

If one set of opposite sides is equal and parallel then both are. The figure is a PARALLELOGRAM and the opposite angles of course must be equal. (see related links below) Parallelograms include rectangles (four right angles) and rhomboids (two opposite acute angles and two opposite obtuse angles). A square is a type of rectangle (all sides equal). A rhombus is a type of rhomboid (all sides equal). Although a square could be considered an… Read More

### A shape with 4 equal-lenth sides opposite sides parallel but no right angles?

A rhombus has 4 sides of equal length, opposing parallel sides, and no right angles

### What is a parrallelogram that is both a rectangle and a rhombus?

A parallelogram has opposite sides equal and parallel. A rectangle means the angles are all 90o as well as opposite sides being equal and parallel A rhombus means all sides are equal in length as well as opposite sides being parallel A parallelogram with angles of 90o (also a rectangle) and all sides equal (also a rhombus) is a square.

### How do you know when a shape is a rhombus?

It has 4 equal sides It has opposite parallel sides It has 2 opposite equal acute angles It has 2 opposite equal obtuse angle It has 2 diagonals that intersect each other at right angles

### Are all parallelograms are rectangles?

Technically they are because they both have 2 pairs of parallel sides but a rectangle has opposite angles of 90 degrees wheres a parallelogram has 2 equal opposite obtuse angles and 2 opposite equal acute angles

### Quadrilateral with congruent sides and no right angles?

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.

### Does a square have any parallel?

Yes a square has equal opposite parallel sides and 4 interior right angles

### What are the sides and angles of a rectangle?

Each pair of opposite sides are of equal measure and are parallel. All the interior angles are right angles.

### Has 4 equal sides its opposite sides are parallel and its angles may be right angles?

I know it must be a rectangle!

### What shape has 4 equal sides and opposite sides are parallel and its angles may be right angles?

a square or a parallelogram

### What are the types of parallelogram?

A parallelogram has opposite sides parallel and equal in length, and opposite angles are equal. Squares, rectangles and rhombuses are all parallelograms.

### Do rectangles have all right angles?

Yes. A rectangle is defined as a quadrilateral with opposite sides parallel and of equal length, and all angles equal to 90° (right angles)

### 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.

### What is the characteristics of a rhombus?

-- four equal sides -- opposite sides are parallel -- opposite angles are congruent -- diagonals are perpendicular

### What are alternate angles?

They are on opposite sides of the transversal line that cuts through parallel lines and they are equal in size Alternate equal angles are formed when a transversal line cuts through parallel lines.

### The angles opposite each other when two lines intersect?

The angles opposite each other are called vertical angles. If you have two parallel lines cut by a transversal line, the angles will be equal.

### What are traits of a rhombus?

A rhombus is a simple quadrilateral with all its sides of equal length. As a result, its opposite sides are parallel, its opposite angles are equal, its adjacent angles are supplementary, and its diagonals bisect each other at right angles.

### Does a trapezoid have 2 pair of opposite congruent angles?

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

### Do all squares have two parallel sides?

All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
