22. Geometrical proof

Proof. (5 marks)

What was the proof for question 22?

You needed to say the opposite angles in a cyclic quadrilateral sum to 180 degrees and that angles at a point on a straight line sum to 180 degrees. Angles EAC and BDC are equal. Angles AEC and DBC are equal and they have the third angle in common.

It's a bit hard to do a vector proof on here. Why don't you ask your teacher to show you tomorrow?

how would u work out Q 6?

Alternate angles are equal.

Base angles of an isosceles triangle are equal.

Angles in triangle sum to 180 degrees.

If you said no to 3b but with the wrong explanation, would u get at least one mark??

ah thanks! could u also say angles on a straight line add up to 180?

No because the exam paper is copyright.
