Extremely new to sailing and was asked this question by a friend and I am totally confused now.

1. If the boat is facing point North and wind is coming NE at 45-50 degrees-----what is the point of sail?

2. If the boat is facing point North and wind is coming at 235 degrees -----what is the point of sail?

Are these reaches? but which ones?

What at 135 degrees?

Please help and thanks,
Emily
