The sides are labelled as Opposite (Opp), Adjacent (Adj) and Hypotenuse (Hyp ... One side and one non-right angle, in which case you can use trigonometry Two sides, where you can apply the Pythagorean ...

Let the obtuse angle MOQ = \(2x\). Using the circle theorem, the angle at the centre is twice the angle at the circumference. Angle MNQ = \(x\) and angle MPQ = \(x\). Therefore angle MNQ = angle MPQ.

c' is the projection of edge c onto the hypotenuse; h is the height of a right triangle drawn from the vertex of right angle A down to the hypotenuse BC. Example 1: Given triangle ABC right angled at ...
