Question

In the given figure, AC is the diameter of a circle with centre 0 and

chord BD intersect AC at 90⁰ at point E. Find the values of p, q and r in

terms of x.​

Answer 1

3 sides of 1 triangle is 180°

in this figure, POB=180°, O=90°(given)

so, P+B+90°=180°

P+B=180-90

P+B=90°(Two angles are same)

means, P=45°(solved)

Now we have to find q

P=q(Alternate interior angle)

so, q=45°(Solved)

now we hve to find r

so (similar to P)

R=45°
