Which of the following quadrilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles?
Which of the following quadrilaterals has a pair of opposite sides parallel?
Which of the following quadrileterals is a reguler quadrilateral?
Which of the quadrilaterals has all angles as right angles, opposite sides equal and diagonals bisect-each other?
Which of the parallelograms has all sides equal and diagonals bisect each other at right angle?
In a parallelogram, opposite sides are equal, opposite angles are equal and diagonals bisect each other. In a rhombus diagonals intersect at right angles. In a rectangle diagonals are equal. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given.
In an isosceles parallelogram, we have:
Which of the following is true the adjacent angles of a parallelogram?
The sides of a pentagon are produced in order. Which of the following is the sum of its exterior angles?
Which of the following is a formula to find the sum of interior angles of a quadrilaters of n-sides?
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides.
Diagonals of which of the following quadrilaterals do not bisect it into two congruent tringles?
