Final answer:
True. The three trigonometric ratios SOH, CAH, and TOA can be used with any type of triangle, not just right angled triangles.
Step-by-step explanation:
True. The three trigonometric ratios SOH (sine = opposite/hypotenuse), CAH (cosine = adjacent/hypotenuse), and TOA (tangent = opposite/adjacent) can be used with any type of triangle, not just right angled triangles. These ratios define the relationships between the angles and sides of a triangle, allowing us to calculate unknown angles or side lengths.
