90 degrees
Quarter turn exactly
Ninety degrees describes a right angle—the angle formed when two lines meet perpendicularly, like the corner of a square or the hands of a clock at 3:00.
In temperature, 90 degrees marks hot weather in Fahrenheit or near-boiling in Celsius.
To turn 90 degrees is to make a sharp quarter-turn: She pivoted 90 degrees and walked away.
