    Don't forget the volume of a pyramid.

    That often catches students out when it appears on a GCSE paper.

    Yes definitely - it's not a hard formula to remember.

    It's come up a few times over the last 5-10 years. E.g. November 2012 Q23 : Only 0.6% of all students got full marks on that question.

    By the way, it's worth looking at the papers at the bottom of here. They show the worst answered questions from recent years.

    My guess is that most people didn't give reasons.

    You would need to give 2 reasons e.g. "angles on a straight line add up to 180" and "alternate angles".

    Or "opposite angles" and "adjacent angles in a parallelogram".

    etc.

    Yes it could. The 2016 exam follows the 2014 spec and it's in there. The spec changes next year.
