SE 11 (A)2. In the given figure, a circle isdivided into four equal parts bythe lines AOD, AOC, BOC, CBOD? How many times is theBangle AOB of angle AOC ?dinte 16 equal

Answer»

plz like my answer

Since circle is divided into 4 equal parts and complete circle is 360 degree. AOD=AOC=BOC=BOD= 360/4 = 90 degree. BOD is a straight line = 180 degree. 180 = 2*90AOB = 2 times AOC

Angle AOB is twice the angle AOC.

angle AOC = 45

angle AOB = 90

therefore angle AOB = 2×AOC = 2×45 = 90angle AOB is twice the angle AOB
