Question 12457: it is possible for two lines to intersect in such a way that three of the angles formed have measures of 20, 70, 20. true or false

You can put this solution on YOUR website! solution:
No
when two lines intersect ,then two pairs of vertically opposite angles are formed
so 20 and 20 is one pair of vertically opposite angles
if the third angle is 70 then the fourth angle should be 70
the sum of the angles=20+20+70+70=180
but the total of angles should be 360
so it is impossible for two lines to intersect in such a way that three of the angles are 20,70,20
