FAQs on Formative Assessment: Understanding Quadrilaterals - Advance Learner Course: Mathematics (Maths) Class 7

1. What are quadrilaterals?
Ans. Quadrilaterals are polygons with four sides and four angles. They can be classified into different types based on the lengths of their sides and the measures of their angles.
2. How many types of quadrilaterals are there?
Ans. There are several types of quadrilaterals, including parallelograms, rectangles, squares, rhombuses, trapezoids, and kites. Each type has its own unique properties and characteristics.
3. What is the difference between a parallelogram and a rectangle?
Ans. A parallelogram is a quadrilateral with opposite sides that are parallel, while a rectangle is a type of parallelogram with four right angles. In other words, all rectangles are parallelograms, but not all parallelograms are rectangles.
4. How can I determine if a quadrilateral is a square?
Ans. A quadrilateral is a square if it has four congruent sides and four right angles. Additionally, the diagonals of a square are equal in length and bisect each other at right angles.
5. What are the properties of a rhombus?
Ans. A rhombus is a quadrilateral with four congruent sides. Its opposite angles are equal, and its diagonals bisect each other at right angles. Additionally, the diagonals of a rhombus are perpendicular bisectors of each other.
