A quadrilateral is a two-dimensional enclosed figure with four sides and four angles. Quadrilaterals are also regarded as tetragons and quadrangles, at many a place. Typically, this geometric shape has three types, that are, convex, concave, and complex quadrilaterals. In a quadrilateral worksheet, students get to learn about these types of quadrilaterals in detail and the related concepts by solving sums.

## Types of Quadrilateral

### 1. Convex Quadrilateral

In convex quadrilaterals, every interior angle is less than 180 degrees, and its diagonals exist inside the figure. The following are the examples of this type of quadrilaterals.

Trapezium

Parallelogram

Rhombus

Rectangle

Square

Oblong

Kite

Cyclic quadrilaterals

Bicentric quadrilaterals

### 2. Concave Quadrilaterals

Quadrilaterals with an interior angle of more than 180 degrees and an exterior diagonal are known as concave quadrilaterals. A prominent example of this type of quadrilaterals is a dart. It has a bilateral symmetry like kites, but one interior angle here is reflex. Referring to a quadrilateral review worksheet will help students get a better insight into the concepts of concave quadrilaterals with real-life examples.

### 3. Complex Quadrilaterals

A quadrilateral that has self-intersecting sides is known as a complex quadrilateral. Bow-tie or butterfly are prominent examples of this geometric shape.

In a mathematical approach, angles formed by these intersections are not part of this shape. This geometric shape has two acute interior angles and two reflex angels. Moreover, these two reflex angles appear outside of the shape, which can lead to certain confusions. However, they are still regarded as interior angles.

Furthermore, two line segments here cross and appear to create two additional interior angles; this geometric shape still has just four interior angles. Hence, these self-intersecting line segments do not add any other features to this shape.

### Properties of Quadrilateral

The properties of quadrilaterals are as follows.

Four angles

Four vertices

Sum of all interior angles is 360 degree

1. What is a Line Segment in a Quadrilateral?

Ans. In geometry part of a line bounded by two endpoints is known as a line segment. In the case of a quadrilateral, one can witness mostly three such segments. Firstly, when the two diagonals of any convex quadrilateral act as a line segment and connect opposite vertices of the quadrilateral. Secondly, two bi-medians of convex quadrilaterals connect midpoints of opposite sides. Thirdly, bisectors of any convex quadrilateral act as perpendicular to one of its sides and pass through the midpoint of opposite sides.

2. What is a Bimedian of a Quadrilateral?

Ans. Bimedian of a quadrilateral is a line segment that connects the midpoints of the opposite sides in a quadrilateral. The intersection point here is known as the centroid of vertices of the quadrilateral. Moreover, the bimedians of a quadrilateral and the segment, which connects these two midpoints of a diagonal are concurrent, and the point of intersection bisects them. Additionally, in a convex quadrilateral, there is a dual connection between these bimedians and diagonals. Hence, bimedians with equal length suggest that two diagonals are perpendicular, and if diagonals have equal length, then these bimedians will be perpendicular.

3. What is a Skew Quadrilateral?

Ans. A non-planar quadrilateral is known as a skew quadrilateral. The formula to compute the dihedral angles of a skew quadrilateral from its edge lengths and its angles between its adjacent edges is derived from the works on molecular properties of cyclobutane. Also, the term gauche quadrilateral historically represented skew quadrilaterals. Moreover, this type of quadrilateral, with its diagonals create a tetrahedron. Conversely, every variant of a skew quadrilateral derives from a tetrahedron where pairs of opposite edges are non-existent.
