Which of the following quadrilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles?
Correct Answer : b
Explanation: A rhombus is a parallelogram and a quadrilateral whose opposite sides are parallel and opposite angles are equal.
Area of Rhombus, A = (d1 x d2)/2
The perimeter of Rhombus, P = 4a units
The opposite angles of a rhombus are equal to each other.
In a rhombus, diagonals bisecting each other at right angles.
Diagonals bisect the angles of a rhombus
If the sides of a triangle are produced in order,What is the sum of the exterior angles so formed?
Suppose you have a ∆ABC
All the exterior angles will be equal to
(180A)°
(180B)°
(180C)°
respectively (Angles on the same line) so if you sum it up it will be equal to 540  (A+ B + C )
And by angle sum property A+B+C = 180°
Therefore Sum = 540  180 = 360°
The sum of the measures of the three angles of a triangle is ______.
Angle sum property of a triangle is that sum of 3 angles is 180º
The ________ of a rhombus are perpendicular bisectors of one another.
Find the value of the unknown x in this parallelogram.
The opposite sides of a parallelogram are of ________ length.
It’s a property of parallelogram that opposite sides of a parallelogram are equal and parallel.
Which of the parallelograms has all sides equal and diagonals bisect each other at right angle?
If two adjacent sides of a parallelogram are equal, then it is a rhombus.. A quadrilateral whose diagonals bisect each other at right angles is a rhombus.
In square all sides are equal and every angle is right angle.
Which of the following quadrilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles?
Rhombus, is a quadrilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles. A rhombus is a a parallelogram and a quadrilateral whose opposite sides are parallel and opposite angles are equal.
