Question

If John starts at one point on a merry go round, and then rides around once so that he ends up in the same spot that he started. What can be said about the angle that the merry go round rotated?

• A. Complete angle
• B. Measures ${360}^o$
• C. Full angle
• D. Straight angle

Answer 1

Answer: (A), (B), (C)

Full angle


John ended up in the same spot that he started which means that the merry go round completed one full circle.

$\underset{–}{\text{Full angle:}}$
An angle whose measure is exactly ${360}^o$
It is also known as $\text{complete angle or full angle}$.


Therefore, the angle that the merry go round rotated is :
$\bullet$ A full angle
$\bullet$ A complete angle
$\bullet$ Measures ${360}^o$

Hence, options (a.), (b.) and (c.) are correct.
