Need help with SAT Geometry

<p>Im scoring between 720-770 on the SAT Math. I really need help with SAT triangle geometry. Are there any review sites that deal with properties of triangles?</p>

<p>This is a quantative comparison question
In triangle ABC, AB=3, BC=4, AC=6.</p>

<p>The length of the altitude to base AB
vs
The length of the altitude to base AC</p>

<p>Area of Triangle=.5(Base)(Length of Altitude).
(Length of Altitude)=2(Area of Triangle)/(Base), so when the Base is smaller, the Length of Altitude is larger. AB is smaller than AC, so the altitude to AB is greater than the altitude to AC.</p>
