Common mistake
Pythagoras and trigonometric ratios common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Know and apply Pythagoras' theorem and the trigonometric ratios to find angles and lengths in right-angled triangles in two-dimensional figures..
Show the method first, then give the final answer in the required form. Apply this directly to Pythagoras and trigonometric ratios. For Pythagoras, confirm the triangle is right-angled and identify the hypotenuse.
