Question

An angle of 800 terminates in which quadrant?

I

II

III

IV

Answer 1

This angle lies in the I quadrant.

Explanation:

The coordinate axes divide the plane into four quadrants, labelled first, second, third and fourth.

When the angle is more than 360º we can divide the angle by 360º and cut off the whole number part.

If we divide 800º by 360º, the integer part would be 2 and the remaining is 80º. Now we should find the quadrant for this angle.

`(800)/(360)=2(80)/(360)`

When the angle is between 0º and 90º, the angle is a first quadrant angle. Since 80º is between 0º and 90º, it is a first quadrant angle.
