Webby using Pythagoras theorem r = 1 LO = 1 2a LM2 = ON2 + r2 at ON2 = 3 therefore LM = 2 since side opposite to 30° half the hypotunes therefore angle ∠MNO = 30° and angle ∠MLO = 30° too! IN triangle LMO angle ∠M = 180° − (30° + 30°) = 120° since angle X half the centric angle therefore angle X = 60° Share Cite Follow edited May 2, 2012 at 19:00 WebMay 26, 2015 · Take an arbitrary triangle inscribed in the circle and let one of the sides subtend the central angle α. Keeping this side fixed and moving the opposite vertex to form an isoceles triangle, we get a larger triangle, and the two other sides will both subtend the central angle π − α 2.

Circle inscribed in triangle - Mathematics Stack …
WebFirst we will construct the angle bisectors of any two angles of triangle ABC, intersecting at point D, which is the incenter of the given triangle. Now construct the perpendicular from point D to any side of triangle ABC. This intersection is point E. Then to construct the inscribed circle use center D and radius segment DE.
