Supplementary angle add to 180 degrees. So the supplement to a 60 deg angle is 180 - 60 = 120 degrees.
This works with any angle . Tan half angle x bend radius. Eg is for a 154 o/d one and a half diameter 90° at 60°. Tan30x225=129.9.

An acute angle.

with compass.........at 90+60degree angle,,,,,,,,, * * * * * and 90 + 60 = 105??? You need to draw a 90 degree ange and bisect it to give a 45 deg angle. Then add a 60 degree angle. 45 + 60 = 105.

90
If two sides and the included angle of one of one of the triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
