In today's class we fooled around with 30* triangles using SIN ratio. We drew three 30* triangles (1 small, 1 medium, and 1 big) See pictures below...
Small triangle
Note:
Mrs. Armstrong told us that when using a2 + b 2 = c2 we should use Leg2 + Leg2 = Hyp2 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
