## FAQs on RD Sharma Class 8 Maths Solutions Chapter 17 - Understanding Shapes III

1. What is the difference between a square and a rectangle?

A square and a rectangle are types of quadrilaterals. The length of all sides of a square are equal but the length of all sides of a rectangle are not equal. Only the length of opposite sides of a rectangle is equal. All the angles in a square and rectangle measure 90 degrees each and the diagonals intersect each other at 90 degrees. A square and a rectangle are the two most important quadrilaterals and students will study the different features of these quadrilaterals in Class 8 Maths Chapter 17.

2. What is the difference between a trapezium and an isosceles trapezium?

A trapezium is a quadrilateral with one pair of opposite sides drawn parallel to each other. It has four angles, sides and vertices. Hence, a trapezium is a polygon. Whereas an isosceles trapezium is a type of trapezium in which the length of non - parallel sides of a trapezium are equal to each other. The length of opposite sides in a trapezium are not equal to each other. Students must understand the difference between a trapezium and an isosceles trapezium to solve the questions given in Chapter 17 of Class 8 maths.

3. What is the difference between a scalene and a right trapezium?

Scalene and right trapezium are two types of trapezium. Scalene trapezium has all sides and angles measuring different from each other. A right trapezium has at least two right angles in it each measuring 90 degrees. The sides of a right trapezium are also different in length. Students can solve the questions based on a scalene and a right trapezium by understanding the differences between the two. They can refer to the Class 8 RD Sharma textbook Solutions Chapter 17- Understanding Shapes III (Special types of Quadrilaterals) to understand the concepts.

4. What are the properties of a rhombus?

All sides of a rhombus measure equally and the opposite sides are parallel to each other. There can be no inscribing and circumscribing circles within or outside the rhombus. The sum of two adjacent angles of a rhombus equals 180 degrees. A rhombus is also a quadrilateral because it has four sides and four angles. A Rhombus looks like a square but there is a difference between the two figures. Students must visit the Vedantu to know more about a square and a rhombus.

5. What are the properties of a parallelogram?

Opposite sides of a parallelogram are congruent and equal to each other. The consecutive angles are supplementary to each other. Each diagonal bisects the figure into equal and similar triangles. For a better understanding of the concepts, students are recommended to refer to previous year questions and other material available on Vedantu. Students must understand the concepts related to parallelogram because they have to solve different types of questions based on the chapter to score high marks in the exam.
