This topic has its basics in polygons. Try to elicit live examples for quadrilaterals from within classroom, starting from the shape of a textbook. Show the vertices of a rectangular page. Mark three sets of four points on the blackboard, one set being collinear and other non-collinear. Call students to join the points of each set of points. This activity will introduce them to the concept of quadrilateral.

# The word quadrilateral comes from two latin words "quadri" which means a "variant of 4" and 'latera' which means 'side'
Any 4 sided shape is a quadrilateral. A quadrilateral is a 4 sided figure with 4 sides, 4 angles and 4 vertices.
