Small triangle

Note:

Mrs. Armstrong told us that when using a

^{2}+ b

^{2}= c

^{2}we should use Leg

^{2}+ Leg

^{2}= Hyp

^{2}instead, unless it is labeled that way

Medium triangle

Since these are 30* triangles (using Sin) it will have a pattern in the measurements; in other words the hyp will be twice as big as the opp

Large triangle

The adj is effect by the opp of the triangle as you can see through these examples

Relations

Sin : Related to the Y axis

Cos : Related to the X axis

Tan : related to the Y axis divided by the X axis

Here is a chart that will show the relation of the trig ratios
