The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. Quadrilateral is derived from a Latin word in which Quadra means four and Latus means sides. The opposite interior angles of rhombuses are congruent.
Each quadrilateral has four 60 angles. Know how to identify a parallelogram. A parallelogram is any four-sided shape with two pairs of parallel sides where the sides across from each other are the same length.
Always show your workings Recap Remember. The sum of angles in a triangle is equal to 180. The marked versions will indicate the right and obtuse angles and the equal sides.
Diagonals of a rhombus always bisect each other at right angles. The sum of the opposite angles of an inscribed quadrilateral is 180 degrees. A Cyclic Quadrilateral is a four-sided polygon encircled by a circle.
At the point of intersection two sets of congruent vertical angles are formed in the corners of the X that appears. Why do we do Geometry. Four corners all 90 degrees right angles.
