Question

Do an activity to show sum of angles in a triangle is 180​

Answer 1

Step-by-step explanation:

Draw a line on the hardboard and arrange the cut-outs of three angles at a point O as shown in Fig. 3. The three cut-outs of the three angles A, B and C placed adjacent to each other at a point form a line forming a straight angle = 180°. It shows that sum of the three angles of a triangle is 180º.
