Presentation

Activity 2

Teacher give a question in chart‘Draw ∆ABC with AB = 4cm, BC = 5cm and CA = 6cm, draw an isosceles triangle of the same area with one side as AB itself.’

After explaining this question teacher draw the figure in the black board using instrument box.

Activity 3

Teacher show second question in the chart and ask them to write in their notebooks ‘Draw ∆ABC in the first problem. Draw a triangle of same area with one side as AB and < B =30o’

Most pupil answers correctly

Pupil write question in their note books.

Pupil observes Then draw the figure in their note books

Pupils write in their book.And try to draw the figure.
