To find the are of a triangle you would have to
use Heron's formula by first finding S and then
using the 2nd part of Heron's formula to find all
the sides
These formulas are used with an SAS triangle.
There are 3 formulas because each formula
helps you find a different angle in the triangle.
How these formulas
are used to find a angle
These equations/ functions are used when
trying to find angles in SSS or SAS triangles.
There are four cases that can be used to solve
an oblique triangles. ASA,SAA,SSA.
You can use trigonometric functions to
prove trigonometric identities.
Odd identities reflect over the origins
while Even identities reflect over the
X-axis.
Sum and Difference formulas can help you
find angles that could not on the unit circle.
You use double angle and half
angle formulas to solve trig functions
Pythagorean identifies are modeled
off of the Pythagorean theorem.
