My answer was B because, the angles A and C are 45 each because the sides are equal, and the angle B will be 90
We know that if it is 90, the line AC should be the diameter, hence the answer is B
Can you tell me why its D?
How do you know? How do you also know that the triangle is right-angled?
Oh yeah, I’m sorry. I assumed A and C were 45 but they could be 60 or whatever. Right. Thanks
