The following proof demonstrates: So, we have proven that the opposite angles of a parallelogram are congruent. The diagonals bisect the angles. 4) If in a quadrilateral, each pair of opposite angles is equal then it is a parallelogram. Give a reason. The length of AB is equal to the length of DC. This means that pairs of angles directly across from each other are of equal magnitude. 9th - 10th grade . BC = AD = 4x - 10 = 4 times 15 - 10 = 60 - 10 = 50. The first person to prove this fact about forces was Isaac Newton in his Principia Mathematica. The is called that parallelogram force law and is extremely useful in physics and engineering, fields where vector addition is common. Mathematics. 2 years ago.
