You need to know all the theroms on the Junior Cert course. But you only need to know 5 theroms in great detail, just google it, it should come up with a list of 19 or so theorms.

Everything you need for Geometry and Trigonometry is listed here.

1) Each exterior angle in a triangle is the sum of the interior opposite angle
2) The angles in a triangle add up to 180 degrees
3) Opposite sides and opposite angles in a parallelogram are equal
4) The angle at the center is twice the angle at the circumference standing on the same arc
5) In a right angled triangle, the hypotenuse squared is equal to the sum of the other sides squared (Pythagorean theorem)

Hopefully #4 or #5 of my previous post come up. They are the worth the most marks out of the 5 and are an easy few percent!

I've heard from one teacher (now mind, this wouldn't be the best teacher in Ireland), that the 'square method' for Pythagorus' theory isn't accepted by examiners anymore.

Could anyone shed some light on this claim?
I would like to disregard this teacher, but I'd hate to be wrong!
