For individual or collaborative investigation (Exercises 65 – 68)

The figure shows a 45° central angle in a circle with radius 4 units. To find the coordinates of point P on the circle, work Exercises 65–68 in order.Use the trigonometric ratios for a 45° angle to label the sides of the right triangle you sketched in Exercise 65.

(Reference Exercise 65)

Sketch a line segment from P perpendicular to the x-axis.
