Mensuration and calculation exam tips

Exam tips

• Congruence and similarity calculations exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [Higher only] Include relationships between lengths, areas and volumes in similar figures..

  This keeps the answer actionable and aligned to Congruence and similarity calculations, rather than giving generic revision advice.

• Pythagoras and trigonometric ratios exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [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.. If using Pythagoras, mention the right-angled triangle and the hypotenuse.

  This keeps the answer actionable and aligned to Pythagoras and trigonometric ratios, rather than giving generic revision advice.

• Pythagoras and trigonometric ratios exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [Higher only] Apply Pythagoras and trigonometric ratios to right-angled and general triangles in two and three dimensions where possible.. If using Pythagoras, mention the right-angled triangle and the hypotenuse.

  This keeps the answer actionable and aligned to Pythagoras and trigonometric ratios, rather than giving generic revision advice.

• Exact trigonometric values exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [Higher only] Know exact values of sin and cos for 0, 30, 45, 60 and 90 degrees..

  This keeps the answer actionable and aligned to Exact trigonometric values, rather than giving generic revision advice.

• Exact trigonometric values exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [Higher only] Know exact values of tan for 0, 30, 45 and 60 degrees..

  This keeps the answer actionable and aligned to Exact trigonometric values, rather than giving generic revision advice.

• Sine and cosine rules exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [Higher only] Know and apply the sine rule and cosine rule to find unknown lengths and angles..

  This keeps the answer actionable and aligned to Sine and cosine rules, rather than giving generic revision advice.

• Area of any triangle exam tip 1

  Write the method before the answer so the examiner can follow each step. Apply this to [Higher only] Know and apply Area = 1/2 ab sin C to calculate the area, sides or angles of any triangle..

  This keeps the answer actionable and aligned to Area of any triangle, rather than giving generic revision advice.
