this pdf covers types of quadrilaterals and their property. n geometry a quadrilateral is a four-sided polygon, having four edges and four corners. The word is derived from the Latin words Quadri, a variant of four, and latus, meaning "side".
1. What is Quadrilateral? In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow. Properties of a Quadrilateral: ● A quadrilateral has 4 sides, 4 angles and 4 vertices. ● A quadrilateral can be regular or irregular. ● The sum of all the interior angles of a quadrilateral is 360°.
2. Types of Quadrilaterals Quadrilaterals can be classified into Parallelograms, Squares, Rectangles and Rhombuses. Square, Rectangle and Rhombus are also Parallelograms. Here’s a list of the types of quadrilaterals with their name, pictures and properties: Name of the Quadrilateral: Picture of Quadrilateral: Properties of the Quadrilateral: Parallelogram Opposite sides are parallel. Opposites sides are equal. Opposite angles are equal.
3. Square All sides are equal. All angles are equal and measure 90°. Rectangle Opposite sides are parallel. Opposites sides are equal. All angles are equal and measure 90°. Rhombus All sides are equal. Opposite angles are equal.
4. Trapezoid Opposite sides are parallel. Adjacent angles add up to 180°. Fun Facts ● The word quadrilateral has originated from two Latin words quadri which means “four” and, latus meaning “side”.
