Which of the following are the coordinates of the point.

Which of the following are the coordinates of the point.

Which of the following are the coordinates of the point.

The polar coordinate system is based on a point, called the ______ and a ray, called the _______ axis.

• pole, polar

• radias, x

• pole, x

• radias, polar

Which of the following are the coordinates of the point.

Which of the following are the coordinates of the point.

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

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

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

• True

• False
