Did you know?
WebLike all other quadrilaterals, the sum of all the angles of a parallelogram is 360°. The adjacent or the adjoining angles of a parallelogram add up to 180°. Therefore, ∠A + ∠B = 180°, ∠B + ∠C = 180°, ∠C + ∠D = 180°, and ∠D + ∠A = 180°. The diagonals of a parallelogram bisect each other. Here, OB = OD, and OA = OC.

Webthe little squares in each corner mean "right angle". A square has equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits … WebSep 27, 2024 · How many angles are congruent on a parallelogram? You have learned that a parallelogram is a closed, plane figure with four sides. It is a quadrilateral with two pairs of parallel, congruent sides. Its four interior angles add to 360° and any two adjacent angles are supplementary, meaning they add to 180° . Opposite (non-adjacent) angles are ...
WebMay 10, 2024 · Shwetank Mauria. May 10, 2024. As adjacent angles of a parallelogram are supplementary and opposite angles are equal, if one angle is obtuse, adjacent angle would be acute and opposite angle would be obtuse. Hence, a parallelogram can have no more than two obtuse angles. Web(This also means that a quadrilateral has exactly four vertices, and exactly four angles.) Some examples of quadrilaterals: Discussions of 2-D shapes sometimes refer only to the boundary (the line segments that form the edges of the figure) or to the interior as well.
WebIF 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. IF a parallelogram has 4 equal sides, then it is a rhombus. All parallelogram rules apply plus the diagonals are perpendicular bisectors of each other.
WebFeb 2, 2024 · The answer is 75. We use the formula that says the area is equal to ½ times the product of the lengths of the diagonals times the sine of the angle between them. As our diagonals are perpendicular, the angle between them is 90° and sin 90° = 1. Hence, the calculation we need to perform is ½ × 10 × 15 = 75.
