Given an isosceles triangle ABC (AB = AC), \(\widehat{A}\) = 108^o. AD and BE are the bisectors of angle A and B, BE = 10cm. Caculate AB.

Given two adjacent angles AOB and BOC. The sum of measure of them is equal to 160^o and the measure of angle AOB is equal to 7 times the measure of angle BOC

a)Find the measure of each angle

b)Inside angle AOC, draw ray OD such that angle COD=90^o. Prove that OD is the bisector of angle BOA.

c)Draw the opposite ray OC' of ray OC. Find the measure of 2 angles AOC and BOC' then compare them
