Q2
These are two slides in a park.
(i) Which slide has a larger angle?
(ii) Which slide do you think is safer for the little boy? Why?
Answer. (i) Slide 1 has a larger angle.
(ii) As slide 1 has a larger angle and steeper than slide 2, there will be more chances for the boy to
get hurt while sliding on slide 1. Thus, slide 2 would be safer for the little boy than slide 1.

Q1 Shapes and Towers Look for triangles in the pictures below.
(i) From the activity ‘Changing Shapes’ can you guess why triangles are used in these towers,
bridges etc?
(ii) Look around and nd out more places where triangles are used.
Answer. The triangles are used in the towers and bridges so as to make them strong. We know that
a triangle is the strongest polygon out of all the other polygons. The angles can get changed in
other polygons. However, in a triangle, the angles can not change once the triangle is built.
