Degree: The basic unit of measure for angles is the degree. And then, if you get all the way to 180 degrees, your angle actually forms a … Then using a compass, we use this as a base to construct an equilateral triangle. A good way to start thinking about the size and degree-measure of angles is by picturing an entire pizza — that’s 360° of pizza. Constructing 75° 105° 120° 135° 150° angles and more. Now set the point of the compass somewhere on the circle, call that point P, and draw an arc whose radius is again R. Call the intersections of that arc with the original circle by the names S and T. Use a straight-edge to draw SO, PO and TO; angle TOS is 120 degrees and angle SOP is 60 degrees. One Degree. It first creates a radius of the circle, then constructs a perpendicular to the radius at the given point. A Euclidean construction You can get a 105 degree angle by adding the 90 degree angle and the 15 degree angle. At 90 degrees, you have a right angle. is the same as an angle of.
