CLOCKS

The face or dial of a watch is a circle whose circumference is divided into 60 equal parts called minute spaces.

A clock has two hands, the smaller one is called the hour hand or short hand while the larger one is called the minute hand or long hand.

ü In 60 minutes, the hand gains 55 minutes on the hour hand.

ü In every hour, both hands coincide once.

ü The hands are in the same straight line when they are coincident or opposite to each other.

ü When the two hands are at right angles, they are 15 minutes spaces apart.

ü When the hands are in opposite directions, they are 30 minutes spaces apart.

ü Angles traced by hour hand in 12 hrs=360⁰.

ü Angles traced by minute hand in 60 min. =360⁰.
