What is a quadrilateral?

A quadrilateral is a geometric figure that has four sides and four angles. It can be of different shapes and sizes, including squares, rectangles, parallelograms, trapezoids, and rhombuses, among others.

How many sides does a quadrilateral have?

A quadrilateral has four sides.

What is the sum of the interior angles in a quadrilateral?

The sum of the interior angles in a quadrilateral is always 360 degrees.

Can all sides of a quadrilateral be of equal length?

Yes, all sides of a quadrilateral can be of equal length only if the quadrilateral is a rhombus. A rhombus is a type of quadrilateral in which all four sides are of equal length.

How many diagonals does a quadrilateral have?

A quadrilateral has two diagonals.

Is a square a type of quadrilateral?

Yes, a square is a type of quadrilateral, as it is a four-sided polygon with four right angles and four equal sides.

Can a quadrilateral have only one pair of parallel sides?

No, a quadrilateral cannot have only one pair of parallel sides. In order for a shape to be classified as a quadrilateral, it must have four sides. Additionally, a quadrilateral with only one pair of parallel sides would be classified as a trapezoid, not a generic quadrilateral, as a trapezoid is defined by having one pair of parallel sides.

Are all quadrilaterals convex?

No, not all quadrilaterals are convex. A convex quadrilateral is a quadrilateral where all its interior angles are less than 180 degrees. However, concave quadrilaterals have at least one interior angle greater than 180 degrees, causing it to have at least one concave vertex.

What is the difference between a rhombus and a rectangle?

The main difference between a rhombus and a rectangle is their angles. A rhombus has all four sides of equal length but its angles are not necessarily right angles, while a rectangle has four right angles but its opposite sides are of equal length.

Can a quadrilateral have right angles but no parallel sides?

No, a quadrilateral cannot have right angles but no parallel sides. A quadrilateral with right angles must be a rectangle, and rectangles by definition have opposite sides that are parallel. Therefore, a quadrilateral with right angles must have at least two pairs of parallel sides.
