Quick Q&A Before You Revise
How do I decide which side is base and which is perpendicular?
They are named relative to the chosen acute angle. The side opposite the angle is the perpendicular, the side next to the angle is the base, and the longest side is the hypotenuse.
What must I memorise from this chapter?
Memorise the six definitions, the reciprocal and quotient relations, the standard values for 0, 30, 45, 60, and 90 degrees, and the complementary angle identities.
