• decagon

• nonagon

• pentagon

the given polygon is

• convex quadrilateral

• concave quadrilateral

The sum of all the angles of a pentagon is

• 10

• 18

• 8

• 5

Chose the incorrect option.

• In a parallelogram opposite angles are equal.

• In a parallelogram opposite sides are equal.

• Adjacent angles of a parallelogram are complementary

• adjacent sides of a parallelogram are parallel

The value of x,y,and z in the given figure in the correct order are

• 80,100,80

• 100,80,80
