Curve followed by M(x,y) such that <AMB = 30 or 60 or any other angle

Question

So imagine two point A and B.

If we draw a circle C with diameter AB, and have M be a point on this circle, then Angle AMB will always be 90

We can define C as the curve followed by M(x,y) such that Angle AMB = 90. C is then a circle.

But would the curve looks like if we define the angle AMB=30 or 40 or 120?

Would it be an ellipse? A hyperbola? A parabola? Something else?what?

I tried to use geogebra to trace M but I failed, if you can help on that also it would be great!

Answer 1

It is called major arc segment of a circle or minor arc segment of a circle depending on whether the angle included is acute or obtuse. They can be simply called minor or major arcs. A constant angle is contained in a circle as a geometric property.
