If a ray bisects an angle of a triangle, then it also bisects the side opposite the angle.

If a plane intersects a cylinder, then the intersection must be a circle.

To be true it must be true for ALL cases

First one is true only if you have an isosceles triangle or an equilateral triangle

For the second, if the intersecting plane is not parallel to the base of the cylinder, you will get an ellipse
