About Class 8 Maths NCERT Extra Questions for Understanding Quadrilaterals 

If you have no idea about the topics of this chapter yet, you must go through our revision notes for Class 8 Maths Understanding Quadrilaterals and then practice the NCERT exercise questions of the chapter. You must have a clear understanding of the NCERT chapter questions then only practising the extra questions will benefit you. Given below are some important points related to the chapter that are covered in askIITians NCERT extra questions for Class 8 Maths Understanding Quadrilaterals:

  • Polygon: The term polygon is made by combining two Greek words - Polus + Gonia where Polus means many and Gonia means corner or angle. Hence, a polygon is a shape that has many vertices or angles. 
  • Types of Polygons: Based on their number of sides/ corners/ angles, there are different types of polygons such as:
    • Triangle: A polygon with three sides and three vertices.
    • Quadrilateral: A polygon with four sides and consecutively four vertices.
    • Pentagon: A polygon with five sides and vertices. (Penta stands for five) 
    • Hexagon: A polygon with six sides and vertices. (Hexa stands for six)
    • Heptagon: A polygon with seven sides and vertices. (Hepta stands for seven) 
    • Octagon: A polygon with eight sides and vertices. (Octa stands for eight) 
    • Nonagon: A polygon with nine sides and vertices. (Nona stands for nine) 
    • Decagon: A polygon with ten sides and vertices. (Deca stands for ten)
  • Types of Quadrilaterals:
    • Parallelogram: A quadrilateral with each pair of opposite sides parallel.
    • Rhombus: A parallelogram with sides of equal length.
    • Rectangle: A parallelogram with a right angle.
    • Square: A rectangle with sides of equal length.
    • Kite: A quadrilateral with exactly two pairs of equal consecutive sides
