Answer:In basic triangle trigonometry, we look at three trigonometric functions: sine, cosine and tangent (sin, cos and tan) with right triangles.
Trigonometry formulas triangles
Let us start by naming the parts of this triangle.
θ is one of the angles of the right triangle (but not the right angle!)
h is the hypotenuse - the longest side of the right triangle
o is opposite to the angle
a is adjacent to the angle
The three formulas to rememeber can be summed up in one acronym:
SOH CAH TOA
where s stands for sine, c for cosine and t for tangent.
The three formulas are written below:
