If a bicycle wheel has 48 spokes, then find the angle between a pair of adjacent spokes.

If a bicycle wheel has 36 spokes, then the angle between a pair of adjacent spokes is (a) 10^0 (b) 15^0 (c) 20^0 (d) 12^0

A Ferris wheel has 20 spokes. Find the angle between two consecutive spokes.

Write five pairs of adjacent angles.

If a wheel has six spokes equally spaced, then find the measure of the angle between two adjacent spokes.

Rehman is making a wheel using spokes. He wants to fix equal spokes in such a way that the angles between any pair of consecutive spokes are equal. Help him by copleting the table. Number of spokes 4, 6, 8, 10, 12 Angle between a pair of consercutive spokes 90^@ 60^@......... (i) Are the number of spokes and the angles formed between the pairs of consecutive spokes in inverse proportion? (ii) Calculate the angle between a pair of consecutive spokes on a wheel with 15 spokes. (iii) How many spokes would be needed, if the angle between a pair of consecutive spokes is 40^@ ?

In Fig.14, name all the pairs of adjacent angles.

In Figure, A B C D is a quadrilateral. Name a pair of adjacent sides. Name a pair of opposite sides. How many pairs of adjacent sides are there? How many pairs of opposite sides are there? Name a pair of adjacent angles. Name a pair of opposite angles. How many pairs of adjacent angles are there? How many pairs of opposite angles are there?

In Fig. B. Name the angle that is represented by angle 1. (b) Name all the pairs of adjacent angles.

If veca makes equal angles with the coordinate axes and has magnitude 3,find the angle between veca and each of the three coordinate axes.

Draw a rough sketch of a quadrilateral KLMN. State,(a) two pairs of opposite sides,(b) two pairs of opposite angles,(c) two pairs of adjacent sides,(d) two pairs of adjacent angles.
