1.What is a circle?

Ans:A circle is an enclosed curved line having a point inside, from which every point on the line remains at the same distance.

2.What is an arc?

Ans: The line that connects any two points on the circle is called a chord. Every chord divides the circle into two arcs.

3.What is a diameter?

Ans : Any chord that moves towards the center is a diameter of the circle.Diameter is two times the radius.

4.What is a radius?

Ans:The distance from the center to the edge of a circle.It is half of the circle's diameter.

5.What is the meaning of geometry?

Ans: Geometry is the branch of mathematics that studies planes, figures, lines, and positions, properties, and formulas for the planes, figures, and lines.

6.Which is the biggest chord of circle?

Ans: The diameter is the biggest chord of circle.

7.In how many arcs does every chord divide the circle?

Ans: Every chord divides the circle into two arcs.

8.How many times is a diameter bigger than radius?

Ans: Diameter is two times the radius.

9.One straight angle = …………  degree.

Ans: 180 °

10.What is the measurement of the two supplementary angle?

Ans: The measurement of the two supplementary angle is 180 ° .

11. How many sides ang angles does a triangle have?

Ans: A triangle has three sides and three angles.

12.What is the measurement of the three angles of a triangle?

Ans : The three angles always add to 180°.

13.What are the different types of triangle based on angles?

Ans: Based on angle ,there are three types of triangle. They are : Acute-angled triangle, Right -angled triangle and Obtuse angled triangle.

14. What types of angle does a right angle triangle have?

Ans : In a right angled triangle, only one angle is a right angle, the other two angles are acute angles.

15.What types of angle does an acute angled triangle have?

Ans : In an acute angled triangle, all three angles are acute angles.

16. What types of angle does an obtuse angled triangle have?

Ans : In an obtuse angled triangle, only one angle is an obtuse angle,the other two angles are acute angles.

17.What are the different types of triangle based on sides?

Ans:Based on sides there are three types of triangle. They are :Equilateral, Isosceles and Scalene triangle.

18.What is the name of an angle which is less than 90 °?

Ans: The angle which is less than 90° is an acute angle.

19.What is the name of an angle which is 90 °?

Ans: The angle which is 90° is a right angle.

20.What is the name of an angle which is greater  than 90 °?

Ans:The angle which is greater than 90° is an obtuse angle.

21.What is complementary angle?

Ans: If the sum of the two angles is 90° then the angles are complementary to each other.

22.If the two complementary angle are drawn as adjacent angle which angle is produce?

Ans:If the two complementary angle are drawn as adjacent angle,They will produce a right  angle.

23.What is vertically opposite angle?

Ans: An angle produced by the two rays opposite to the two sides of an angle is called the vertically opposite angle of the given angle.

If two straight lines intersect each other at a point, two pairs of vertically opposite angles are obtained at the point.

24.What is the complementary angle of 75°?

Ans: The complementary angle of 75° is 15°.

25.What is a quadrilateral?

Ans:The figure which has a flat shape with four straight sides is called a quadrilateral.

26.What are tge different kinds of quadrilateral?

Ans:There are 5 kinds of quadrilaterals.They are:Square, Rectangle, Rhombus,Trapezoid, Parallelogram.

27.What is a parallelogram?

Ans:The quadrilateral in which the opposite sides are equal and parallel is called a parallelogram.The opposite angles of a parallelogram are equal.

28.What is a rhombus?

Ans:The quadrilateral which all sides are equal but none of its angle is not a right angle is called a rhombus.In a rhombus the opposite sides are equal each other and opposite angles also are equal.

29.What is a square?

Ans : The quadrilateral in which each side is equal and parallel and angles are right angle is called a square.
