Triangle JKL is equilateral. One side of the triangle, JL, is a diameter of circle M. Which is true about line segments JK and KL?

Because JL is a diameter, the circle’s radius is half the length of JL. In an equilateral triangle, K lies a distance of √3/2 times JL from the midpoint of JL, which is greater than the circle’s radius, so K is outside the circle. Thus JK and KL each have one endpoint on the circle and one outside; neither is a chord, and neither is tangent because each meets the circle at an endpoint while passing into the circle’s interior.
