The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

For this method, you can use the sin function: Height = (Side * sin (Angle)) Assuming that you have a triangle with an angle of 30 degrees and an adjacent side of 8 units, this approach would yield: ...

No matter how much the triangle is enlarged, the opposite divided by the adjacent will always be 0·75. This is because the angle stays the same and the sides stay in the same proportion.
