Answer:
Yes
Explanation:
The answer is yes because all 3 points are on the circle itself. Triangles AXY or TUY would not be considered inscribed because in triangle AXY, none of the points lie on the circle and only 2 of triangle TUY's points lie on the triangle.
So to be considered "inscribed" in a circle, the triangle has to have all points on the circle.
By the way, I got this answer correct on my assignment. So you don't have to worry that it might be wrong. :)
