MCQ 1: For the Cosine Rule of any triangle ABC, the b² is equal to:

  1. a² - c² + 2ab cos A
  2. a³ + c³ - 3ab cos A
  3. a² + c² - 2ac cos B
  4. a² - c² 4bc cos A

MCQ 2: For the Cosine Rule of any triangle ABC, the c² is equal to:

  1. c² + a² + 2ac cos C
  2. a² + b² - 2ab cos C
  3. a² + b² + 2ab cos A
  4. a² - b² + 2ab sin A

MCQ 3: In a triangle ABC, if angle A = 72°, angle B = 48° and c = 9 cm then the Ĉ is:

  1. 69°
  2. 66°
  3. 60°
  4. 63°

MCQ 4: Considering The Cosine Rule of any triangle ABC, the possible measures of angle A includes:

  1. angle A is obtuse
  2. angle A is acute
  3. angle A is right-angle
  4. all of above

MCQ 5: The sine rule for a triangle states that:

  1. a/sin A = b/sin B = c/sin C
  2. sin A/a = sin B/b = sin C/c
  3. a/sin A + b/sin B + c/sin C
  4. 2a/sin A = 2b/sin B = 2c/sin C
