  • Cosine rule to find a side
    If the three side lengths in a triangle are a, b and c, with an angle C opposite the side with length c, then c 2 = a 2 + b 2 − 2 a b cos ⁡ C c^2=a^2+b^2-2ab\\cos C c2=a2+b2−2abcosC.

  • What is the cosine rule for length?

    As per the diagram, Cosine rules to find the length of the sides a, b & c of the triangle ABC is given by; a2 = b2 + c2 – 2bc cos x.

  • What is the cosine rule Igcse?

    $$ c o s C = a 2+ b 2− c 22 a b ​.
    The cosine rule relates the lengths of all three sides in a triangle and the cosine of one of its angles.
    Therefore, the cosine rule is will help us to find: the third side of a triangle when you know two sides and the included angle (the angle between the two known sides)
