Year 10 Interactive Maths - Second Edition. A quadrilateral is a closed plane figure bounded by four line segments. For example, the figure ABCD shown here is a quadrilateral. A line segment drawn from one vertex of a quadrilateral to the opposite vertex is called a diagonal of the quadrilateral. The theorems we have proved can be used to prove other theorems. They can also be used to find the values of the pronumerals in a problem.

## Properties of Quadrilaterals – Rectangle, Square, Parallelogram, Rhombus, Trapezium

In this tutorial on basic geometry concepts, we cover the types and properties of quadrilaterals: Parallelogram, rectangle, square, rhombus, trapezium. Do opposite sides in a quadrilateral have to be equal in order for it to have diagonals that are perpendicular? It is not correct. The diagonals are perpendicular if and only if all the sides are equal as in the case of a rhombus or a square. The diagonals will be perpendicular also if the pairs of adjacent sides are equal as in the case of a kite. However, in a kite the diagonals are perpendicular but the diagonals are not congruent. In a rhombus, rectangle or square for it to have diagonals that is perpendicular and congruent all of its sides must be congruent.

Opposite sides are parallel and equal.

## Quadrilaterals Properties | Parallelograms, Trapezium, Rhombus

Types of quadrilaterals are discussed here: 1. Parallelogram: A quadrilateral whose opposite sides are parallel and equal is called a parallelogram. Its opposite angles are equal. Here LMNO is a parallelogram. LO is parallel to MN.

In this chapter, you will learn more about different kinds of triangles and quadrilaterals, and their properties. You will explore shapes that are congruent and shapes that are similar. You will also use your knowledge of the properties of 2D shapes in order to solve geometric problems. By now, you know that a triangle is a closed 2D shape with three straight sides.
