To verify by paper cutting and pasting, that the sum of interior angles of a quadrilateral is 360˚.
Learning Objective: To understanding the angle sum property of a quadrilateral.
Pre-requisite: Knowledge of a quadrilateral and its interior angles. Idea of a complete angle.
Material Required: A colored sheet of paper, a plain sheet of paper, glue, a pair of scissors, a ruler and
a pencil/pen.
Procedure:
Step 1. On a coloured sheet of paper, draw a quadrilateral PQRS. Mark angles P, Q, R, S as angle 1,
2, 3, 4 respectively.
Step 2. On coloured sheet of paper draw two equal quadrilaterals namely PQRS.
Step 3. Paste on of the quadrilaterals on white sheet.
Step 4. Cut the second quadrilateral PQRS along its sides to divide it into four parts such
that each part contains only one of the angles 1, 2, 3, 4 as shown.
Step 5. Now, arrange all the angles 1, 2, 3, 4 at a point O as shown.
Paste these angles adjacent to other.
