There are many benefits to timing your practice, including:

I created a template that gather all the geometry formulas that appear on the GMAT (if i missed any please tell!). I use it every week in order to ensure that I remember all of them.

I think it could be helpful for some of you so I decided to share.

Area of Isosceles Triangle = 1/2[(leg)^2] (from Geometry Formulas.pdf)

I haven't been able to give myself any convincing explanation of this formula...

Well that's because it's not true.

It should be area of isosceles right triangle = 1/2*(leg)^2, simply because area of right triangle equals to 1/2*leg1*leg2, and since in isosceles right triangle leg1=leg2, then this formula becomes area=1/2*(leg)^2.

I'd also add one more element to Coordinate geometry. The coordinates of a point P on line joining two points A(x1,y1) and B(x2,y2) such that PA:PB is in the ration m:n would be ((mx2+nx1)/(m+n),(my2+ny1)/(m+n)).
