    I got 1 as the answer. Took me a while to cop it though. I'd even drawn the height line and didn't notice it made the right angle ha.

    yeah that answer is 1. our supervisor told us, was so happy i got it right, cas 1 seemed like such a wrong answer since the other sides were x + 1 and all

    (c)(ii):

    The lengths of the sides of an isoceles triangle are sq (x^2 +1), sq (x^2+1) and 2x. Taking 2x as the base, find the perpendicular height of the triangle.

    Yes the answer is 1.

    It's Pythagoras' theorum

    If you draw in the perpendicular bisector on a isosceles triangle you form two congruent right-angled triangles. You know two sides so you can find the third.
