Question (1)

A circle divides plane on which it lays into (   …     ) parts.

Question (2)

A circle is a plane figure? True or false

Question (3)

An exterior angle of a triangle measures 110 degrees and its interior opposite angles are in the ratio 2:3. Find the angles of the triangle.

Solution and Answers:

Q 1.

A circle divides the plane on which it lies into three parts. They are :

(i)                 Inside the circle, which is also called the interior of the circle.

(ii)               The Circle, and

(iii)             Outside the circle, which is also called the exterior of the circle. The circle and its interior make up the circular region.

 

Q 2. 

True

	A

 

Q 3.

Solution:

Interior opposite

 angles are in the ratio of 2:3

	110

 

(A+B)  = 110

C

B

Sum of ratios = 2+3 =5                      

So, one Angle = (110/5) x2 = 44

Another angle= (110/5) x3 = 66

Interior angle C = 70
