What is the Law of Cosines?

Back

The Law of Cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. It is used to find a side or angle in any triangle. Formula: c² = a² + b² - 2ab * cos(C).

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of a transversal and inside the two lines. They are equal when the lines are parallel.

What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles that are on the same side of the transversal and inside the two lines. They are supplementary when the lines are parallel.

What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Formula: a² + b² = c².
