Writing down these with your pencil will prevent silly mistakes and help you to see how to approach harder problems.
What are formulas?
200
This is the formula used to calculate area.
What is A=lw or A=bh ?
200
This is the word used for ANY line segment from the center of a circle to a point on the circle.

This is the Pythagorean theorem, which shows the relationship between the lengths of the sides of a right triangle.
What is a^2+b^2=c^2 ?
300
Opposite angles formed at the intersection of two lines, called vertical angles, are related in this way.
What is equal?
400
This is the strategy that can be used on ANY question, but is best for those asking "how much" or "how many" with answer choices around in order from smallest to biggest (or vice versa).
