i) 0.3 x 0.7
ii) 0.5 x 0.5

Activity 2: To compare the marks obtained in all the subjects by a student in the first and second term examination by drawing a bar graph using paper cutting and pasting.

Activity 3:(a) Identify the conditions under which given pair of angles are complimentary.
(b) Identify the conditions under which given pair of angles are supplementary.

Activity 4: To verify that if two lines intersect at a point, then each pair of vertically opposite angles are equal by paper cutting and pasting.

Activity 5: To verify that if two parallel lines are cut by a transversal, then
i) each pair of corresponding angles are equal
ii) each pair of alternate interior angles are equal
iii) each pair of interior angles on the same side of transversal are supplementary by paper cutting and pasting.

Activity 6: (a) To get a median of a triangle from any vertex, by paper folding. To verify that in a triangle, medians pass through a common point, by paper folding.
