Answer 1

$\underline{\underline{\maltese\: \: \textbf{\textsf{Answer}}}}$

I) The hour hand of clock revolves by 90° or 1 right angle when it goes from 10 to 1.

• The hour hand of clock revolves by 270° or 3 right angles when it goes from 12 to 9.
• The hour hand of clock revolves by 180° or 2 right angles when it goes from 12 to 6.

ii) if the hour hand starts from 7 and turns through two straight angles it will reach 7 because two straight angles make four right angles.
