WebThe ratio of two adjacent angles of a parallelogram = 4 : 5. Let 4x and 5x the angles. Then, 4x + 5x = 180° {the sum of two adjacent angles of a parallelogram is supplementary} 9x = 180°. x = 20°. Therefore, the angles are 4 × 20° = 80° and 5 × 20° = 100°. WebThere are some special properties of a parallelogram that make it different from the other quadrilaterals. Observe the following parallelogram to relate to its properties given below: The opposite angles of a parallelogram are congruent (equal). Here, ∠A = ∠C; ∠D = ∠B. All the angles of a parallelogram add up to 360°.

Web21 aug. 2024 · A parallelogram has four sides total. The most recognizable parallelogram is the square; however, a parallelogram can be many shapes: A square is the parallelogram that has four equal sides. The opposite sides are parallel and all corners of the square form a right angle. Do all parallelograms have 4 sides? WebQuadrilateral. A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ... ipb for dummies
