To prove HL you need to prove that the same leg of both of the triangles are congruent and the hypotenuse, and they must be right triangles.
HL- I'd the hypotenuse an a led if a right triangle are congruent to the hypotenuse and a led if another right triangle, then the triangles are congruent.
For SAS, the two sides and the included angle of one triangle are congruent to two sides and the included angle if anther triangle, then the two triangles are congruent.
So you basically need to prove that a side, angle, and a side are congruent......
I really hope that this made sense.....tell me if not.

The exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5
<h3>Solving trigonometry identity</h3>
If an angle of measure 120 degrees intersects the unit circle at point (-1/2,√3/2), the measure of cos(120) can be expressed as;
Cos120 = cos(90 + 30)
Using the cosine rule of addition
cos(90 + 30) = cos90cos30 - sin90sin30
cos(90 + 30) = 0(√3/2) - 1(0.5)
cos(90 + 30) = 0 - 0.5
cos(90 + 30) = 0.5
Hence the exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5
