What are the properties of a 1.trapezium 2.rhombus3.parallelogram4. Rectangle and square |
| Answer» Trapezium:\tLike other quadrilaterals, the sum of all the four angles of the trapezium is equal to 360°\tA trapezium has two parallel sides and two non-parallel sides\tThe diagonals of regular trapezium bisect each other\tThe length of the mid-segment is equal to half the sum of the parallel bases, in a trapezium\tTwo pairs of adjacent angles of a trapezium formed between the parallel sides and one of the non-parallel side, add up to 180 degrees.Rhombus:\tAll sides of the rhombus are equal.\tThe opposite sides of a rhombus are parallel.\tOpposite angles of a rhombus are equal.\tIn a rhombus, diagonals bisect each other at right angles.\tDiagonals bisect the angles of a rhombus.\xa0Parallelogram:\tThe opposite sides are congruent.\tThe opposite angles are congruent.\tThe consecutive angles are supplementary.\tIf anyone of the angles is a right angle, then all the other angles will be the right angle.\tThe two diagonals bisect each other.\tEach diagonal bisects the parallelogram into two congruent triangles. | |
