Answer:
When you will draw two parallel lines , and a Transversal cutting it
The Transversal may cut the parallel lines in two ways
(a)The Transversal may be perpendicular to two lines
(b) The Transversal may cut the two parallel lines which are not perpendicular.
In both the cases , 8 angles will be formed and sum of all the angles will be 720°.
When you will consider case a , there will be exactly 8 right angles.
When you will consider case b, there will be no angle equal to 90°, but sum of total angle is 720°, which will be equal to 8 right angles.
