Polar Coordinates

In the polar coordinate system, we were plotting points based on an ordered pair of (x,y).

• True

• False

The sign of r is very important in locating the exact position of the point.

• True

• False

If r is zero (r = 0) then the point lies at the pole regardless of θ.

• True

• False

If r is negative (r > 0) then the point lies on the ray opposite of the terminal side of θ.

• True

• False

Polar coordinates can have multiple coordinates representing the same point by adjusting the angle θ or the sign of r and the angle θ.

• True

• False

In polar coordinate, the origin is called as pole.

• True

• False

If r is positive (r < 0) then the point lies on the terminal side of θ.

• True

• False

If r is negative (r < 0) then the point lies on the ray opposite of the terminal side of θ.

• True

• False

If r is zero (r = 0) then the point lies at the

polar axis regardless of θ.

• True

• False

Rectangular Coordinate is also known as Polar Coordinates.

• True

• False
