Trigonometry
The measure of triangles
It has two parts pythagoras and
right angles
trig ratios It only works with
Pythag 3Sides
TrigRatios langle 2sides
We use standard namingsystem sides based on the angle
We are
a
interested for the
Hypotenus opposite to
the rightangle
opposite to the
ridge Adjacent Next to theangle
µÉ opposite
O H
opposite opposite to the
angle
Adjacent A
There are three trig ratios that we use they are
sine cosine tangent
sine opposite cos Adjacent tan opposite
Hypotenuse Hypotenuse Adjacent
The will give the ratio between the two sides we select
trig function of an angle
the ratio forthe question based on the 2 sides we are interested in
