Question 1
1 / -0

Greatest chord of a circle is called its

A
diameter

B
secant

C
chord

D
radius

Solution

Since diameter is the longest segment that can be drawn in a circle(touching the circle at both ends), therefore it is the longest possible chord also.
Question 2
1 / -0

AB is a chord of a circle with radius ‘r’. If P is any point on the circle such that ∠APB is a right angle , then AB is equal to

A
2r

B
3r

C
r²

D
r

Solution

Since the angle subtended by the diameter or the semicircle is a right angle, therefore the AB is nothing but the diameter. Hence, it is equal to 2r, r being the radius.
