Not all quadrilaterals have parallel sides. Here is our final member of the quadrilateral family. A kite has got two pairs of sides next to each other that have equal length. But none of the sides are parallel.

## Are the opposite sides of a kite always parallel?

However, their congruent sides were always opposite sides. Kites have two pairs of congruent sides that meet at two different points. … (1) The diagonals of a kite meet at a right angle. (2) Kites have exactly one pair of opposite angles that are congruent.

## What shapes have opposite sides that are parallel?

A parallelogram is a quadrilateral with opposite sides parallel. The first figure above is a parallelogram. There are a few special features of parallelograms. One is that each pair of parallel sides is congruent.

## Does a rhombus have 4 right angles?

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles.

## Can a kite have a right angle?

Thus the right kite is a convex quadrilateral and has two opposite right angles. If there are exactly two right angles, each must be between sides of different lengths. All right kites are bicentric quadrilaterals (quadrilaterals with both a circumcircle and an incircle), since all kites have an incircle.

## How do you prove parallel lines?

If two parallel lines are cut by a transversal, then corresponding angles are congruent. If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel.

## Does a parallelogram have four right angles?

A square is one of the most basic geometric shapes. It is a special case of a parallelogram that has four congruent sides and four right angles. A square is also a rectangle because it has two sets of parallel sides and four right angles. A square is also a parallelogram because its opposite sides are parallel.

## What two Quadrilaterals have no parallel sides?

In India and Britain, they say trapezium ; in America, trapezium usually means a quadrilateral with no parallel sides.) An isosceles trapezoid is a trapezoid whose non-parallel sides are congruent. A kite is a quadrilateral with exactly two pairs of adjacent congruent sides.

## What are 4 sided shapes called?

quadrilaterals

## What is a 4 sided shape with unequal sides?

A quadrilateral is a square if and only if it is both a rhombus and a rectangle (i.e., four equal sides and four equal angles). Oblong: a term sometimes used to denote a rectangle that has unequal adjacent sides (i.e., a rectangle that is not a square). Kite: two pairs of adjacent sides are of equal length.

## Does a rhombus have a 90 angle?

Explanation: As a parallelogram, rhombus has a sum of two interior angles that share a side equal to 180∘ . Therefore, only if all angles are equal, they all are equal to 90∘ . That equality of all angles makes a square out of rhombus.

## Does a rhombus have 4 90 degree angles?

No, because a rhombus does not have to have 4 right angles. … A square has got 4 sides of equal length and 4 right angles (right angle = 90 degrees). A Rhombus has got 4 sides of equal length and opposite sides are parallel and angles are equal.

## Does a trapezoid have 4 right angles?

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
