Draw an angle < Aob = 100° , with the same vertex 0, draw <Boc = 80° such that OB is common to two angles.
you will observe that the above angles form a straight angle that is 180° thus, the angles 100° and 80° are supplementary to each other . Are 130° and 70° supplementary angles ? why? why not ?
