For Geometry Ques 16b)
From my understanding, in order for me to prove 2 lines parallel, I need to have corresponding angles, alternating angles or supplementary angles. The following attachment is my working. The angle with the same colour marking is equal.
But I am stuck with to prove the angle on the line EF to be related with my other marked angles.
There is another attachment of my working for the other question.
Thank you.
I see everybody as my Mentor as they guide me in different ways.
