If angles P, Q, R, and S of the quadrilateral PQRS, taken in order, are in the ratio 3 : 7 : 6 : 4, then PQRS is a
rhombus
parallellogram
trapezium
kite
Example for a regular polygon is
Square
Rectangle
Triangle
None of these
The sum of the angles of any two adjacent angles in a parallelogram measures
90o
360o
180o
_____ is always a regular polygon.
Isosceles triangle
Equilateral triangle
Pentagon
The sum of the measures of the four angles of the quadrilateral is
180°
90°
120°
360°
Sum of the angles of exterior angles of a polygon is
720o
600o
The number of sides of a regular polygon, if each of its interior angles is 135°, is given by
4
6
8
10
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
If a quadrilateral has two adjacent sides equal and the other two sides equal then it is called
parallelogram
square
rectangle
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°.
