How to measure an angle between 3 points in Access?

Enter values for Azimuth 1 (1), and Azimuth 2 (2).

The software calculates the following values: the azimuth halfway between the entered values (3) and the computed angle, measured clockwise between azimuth 1, and azimuth 2.

Select the Side point 1 (1), Corner point (3), and Side point 2 (2).

The software calculates the following values:

• azimuth (4), halfway between Side point 1 and Side point 2, from the Corner point
• inside angle (5) and outside angle (6)
• distance from the corner point to the two side points and the distance from one side point to the other
• azimuth from the corner point to the two side points
• angle between the corner point and each side point, as well as the opposite angle (7)
