1
Q
right triangles side length equation
A
a2+b2=c2
2
Q
special right triangles angles
A
45- 45- 90
30- 60- 90
3
Q
45- 45- 90 step by step
A
one of the 45 sides is 7
then the other 45 equivalent side is 7
and the one across from 90 angle is 7√2
4
Q
30- 60- 90 step by step
A
side oppo from 90 angle is 12
the side opposite form 30 angle is half, 6
side oppo from 60 angle is 6√3
5
Q
theta Θ means
A
represents an angle measurement (basically x for angles)
6
Q
3 trigonometry side types =
A
adjacent
opposite
hypotenuse
7
Q
hypotenuse =
A
acroos right angle
8
Q
adjacent =
A
next to pheta Θ (not hypotenuse)
9
Q
opposite=
A
across from pheta Θ
10
Q
sine of ∠A =
A
opposite/ hypotenuse
11
Q
cosine of ∠A =
A
adjacent/ hypotenuse
12
Q
tangent of ∠A =
A
opposite/ adjacent
13
Q
way to remember ∠A =
A
