It has a measure of 90 degrees. What are some things i should do to impress ? Source. 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. And then, if you get all the way to 180 degrees, your angle actually forms a … Such triangle has the corners with a 30 degree, a 60 degree and a 90 degree angle. And its done in the following steps: 10). Degree: The basic unit of measure for angles is the degree. Construct a Perpendicular Line to a Given Line Through Point on the Line. Constructing an angle Constructing a 60° angle. cos ABC= CB/AB = 1/2 ==> angle ABC = 60 degree. The line joining the center and the intersections forms 90 degree. Next, bisect angle SOV to obtain a point W on the circle, such that angle SOW = angle WOV = 15 degrees. At 90 degrees, you have a right angle. Now you need to bisect the 90 degree angle you just constructed to get two 45 degree angles. Using the properties of a rhombus it can be shown that the angle created has a measure of 30 degrees.
