4
6
8
10
The quadrilateral in which the diagonals bisect each other and they are perpendicular to each other.
Rectangle
Rhombus
Parallelogram
Trapezium
Sum of the angles of exterior angles of a polygon is
360o
180o
720o
600o
Each interior angle of a regular polygon of n sides (n ≥ 3) contains
4n right angles
2(n + 1)/n right angles
2(n - 1)/n right angles
2(n - 2) /n right angles
Opposite sides of a parallelograms are
Equal
Not equal
Supplementary
None of these
In a rectangle ABCD, the diagonal AC = 10 cm then the diagonal BD =
5 cm
10 cm
20 cm
40 cm
One of the angles of a parallelogram measures 63°. Measures of the other three angles of the parallelogram are
63°, 63°, and 63°, because all the angles of a parallelogram are always congruent.
63°, 27° and 27°, because consecutive angles of a parallelogram are complementary and the sum of the measures of the angles of a parallelogram is 180°.
63°, 117° and 117°, because consecutive angles of a parallelogram are supplementary and the sum of the measures of the angles of a parallelogram is 360°.
Cannot be determined
