Use the Law of Cosines to prove that the sum of the squares of the diagonals of any parallelogram equals the sum of the squares of the sides. c2 + d2 = a2 + b2 + a2 + b2 = 2(a2 + b2) . c2 = a2 + b2 − 2abcosC , andd2 = a2 + b2 − 2abcosD .
What is the law of cosines in Algebra 2?
The Law of Cosines is a2 = b2 + c2 - 2bc(cosA).
However, we can rearrange the law to fit our needs.
Always remember that the triangle side on the left of the equation should match the cosine angle on the right side.
What is the answer to the law of cosines?
It is also called the cosine rule.
If ABC is a triangle, then as per the statement of cosine law, we have: a2 = b2 + c2 – 2bc cos α, where a,b, and c are the sides of triangle and α is the angle between sides b and c.
When must you use the law of cosines instead of the Pythagorean Theorem?
When must you use the Law of Cosines instead of the Pythagorean Theorem? The Law of Cosines must be used for any oblique (non-right) triangle.
