If a transversal intersect two parallel lines, the the sum of angles on the same side of transversal (co-interior angles) is always 180°.If a transversal intersect two lines, then the side where the sum of co-interior anglesis less than 180°,that side the lines will converge and intersect each other at a point when those lines are extended and the side where the sum of co-interior angles is more than 180° that side will diverge and cannot intersect each other at any point if extended. That's the euclid's 5th postulate. Thank you

Consider a=x, b=x, c=x By using angle sum property a+b+c=180 i. e x+x+x=180 3x=180 X=180/3 X=60 hence, all angles of equilateral triangle are equal Therefore, a =60„ b=60 „c=60
