The number of sides of a regular polygon, if each of its interior angles is 135°, is given by
4
6
8
10
The sum of the angles of a parallelogram is
180o
540o
300o
360o
Example for a regular polygon is

None of these
A line segment connecting two non - consecutive vertices of a polygon is called
Side
Angle
Diagonal
Height
Sum of the angles of exterior angles of a polygon is
720o
600o
If the diagonal AC, BD of a parallelogram meet at O, then
OA= OC
OA=OB
OA= OD
OA= BD
The quadrilateral in which the diagonals bisect each other and they are perpendicular to each other.
Rhombus
Parallelogram
Trapezium
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

60°
100°
90°
45°
