Arrangement of students in different triangular shapes to understand the concept of Exterior Angle Property of triangles by passing the Ball

Learning Outcomes

1. Students will be able to understand the concept of Exterior Angle Property of Triangles.

 2. Skills of Joyfulness, Self esteem, cooperation will be developed amongst the students.

Description Of Activity

:-  How to Play

                        1. Students of the whole class will be divided into three groups.

                        2. With chalk powder, three different shaped triangles and one Extended side  will be

                             marked to fix the boundary.

                        3. Students will be arranged on these three marked triangles (i.e. scalene triangle, Right

                            Angled triangle and Obtuse angle triangle).

                       4. Each student will pass the ball to the nearby students  and complete the one circle of the

                          process.

                     5. Continue in this way 10 circles will be completed without dropping the ball.

                     6.  In this arrangement sum of two opposite interior interior angles will be measured

                          and Exterior angle. Table will be prepared  for  Verification of the concept that Sum of  the two opposite interior angles of a triangle is equals to the exterior angle .
