Question

What will be the angle subtended by the chord at a point on the major arc if the chord is equal to the radius of the circle
​

Answer 1

Answer:

30

Explanation:

because when we will join that chord(=radius) with centre, it will become a equilateral triangle (try drawing it's sketch) u will get it because it's all sides are equal to radius OR all sides are equal.

so angle at centre will be 60°.because all angles are equal of an equilateral triangle & by angle sum property it comes 60°

after this acc... to the property of circle that

"angle subtended by an arc at the centre is double the angle subtended by it at any other point" so by converse of this-- we get( let angle at centre be X and at another point be Y)

now we get:

X =2Y

OR

60°=2Y

Y=60÷2

Y=30

so angle subtended by an chord(=radius) at another point on the circle is 30°.
