1. What are quadrilaterals?
Ans. Quadrilaterals are closed geometric figures with four sides and four vertices. They are two-dimensional shapes that have four straight sides, and the sum of their interior angles is always equal to 360 degrees.
2. How many types of quadrilaterals are there?
Ans. There are several types of quadrilaterals, including squares, rectangles, parallelograms, rhombuses, trapezoids, and kites. Each type has unique properties and characteristics.
3. What is the difference between a square and a rectangle?
Ans. Both squares and rectangles are quadrilaterals with four sides and four right angles. However, a square has all sides of equal length, while a rectangle has opposite sides of equal length. In other words, all sides of a square are equal, whereas only opposite sides of a rectangle are equal.
4. How can we determine if a quadrilateral is a parallelogram?
Ans. A quadrilateral is a parallelogram if both pairs of opposite sides are parallel. Additionally, the opposite sides must also be of equal length. These two conditions together make a quadrilateral a parallelogram.
5. What is the sum of the interior angles of a quadrilateral?
Ans. The sum of the interior angles of any quadrilateral is always equal to 360 degrees. This means that if you add up the measures of all the angles inside a quadrilateral, the total will always be 360 degrees.
