WebThe three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent. WebParallelogram Definition. A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. The Sum of all the interior angles equals 360 degrees.

WebIf we just had information on one of the angles e.g. 120°, we could work out the other angle is 60°. If the straight line was divided into three angles, all three angles would add up to … WebSo you start with a parallelogram, two pairs of parallel sides, opposite sides are congruent, adjacent angles are supplementary, diagonals bisect each other, and opposite angles are congruent. IF a parallelogram has an angle of 90 degrees (thus all 4 angles are 90) it is a rectangle - all rules of parallelograms apply plus diagonals are congruent. cisco ccna website
