*Draw an angle in standard position that has
the point (-6, 3) on its terminal side.
a. Find the distance from (0, 0) to (-6, 3)
b. Draw a RIGHT TRIANGLE that contains
both points; (0, 0) and (-6, 3).
**NOTE: Any angle in standard position has a ________________________ that can be drawn
from the _______________________ to the _________________________.
