Question

Write the following statements true or false. I. The line segment joining the center of a circle and any point on the circle is the radius of the circle. 1. The point (0, 3) lies on the Y axis. 1. At least 3 lines are needed to create a closed figure. 1. The measure of each angle of the angle of the linear pair must be 90°.​

Answer 1

Answer:

(i) True : Radius is the length of line segment from centre to any point on circumference of circle.

(ii) False : We can draw infinite number of chord by joining any two points on circle since infinite number of points lie on the circle, .

(iii) False : These arcs are called equal arc since these arcs are equal in length.

(iv) True : Diameter is twice the radius of the circle and it is the longest chord.

(v) False : Sector is the region between an arc and the two radii.

(vi) True : Circle lies in a plane since a circle is the locus of a point in a plane which moves in such a way that its distance from a given fixed point is always constant.
