It may but it doesn't have to. It's very easy for a single straight line to cut one
side of a triangle into 1/3 and 2/3 pieces, and then go on to cross another side
of the triangle at its midpoint.
A median of a triangle is a line or segment that passes through a vertex and bisects the side of the triangle opposite the vertex.

An angle bisector of a 90-degree angle is a line or ray that divides the 90-degree angle into two equal angles of 45 degrees each. It is a line that passes through the vertex of the angle and divides it into two congruent angles. In a right triangle, the angle bisector of the right angle will also bisect the opposite side, creating two smaller right triangles.

and is perpendicular to the opposite side.
circumcircle of a triangle is the circle that passes through all 3 vertices. this circle is said to be circumscribe the triangle

Altitude.
A median of a triangle is a line or segment that passes through a vertex and the midpoint of the side opposite that vertex. The median only bisects the vertex angle from which it is drawn when it is an isosceles triangle.
yes
It is a straight line which passes through the vertex of the angle and divides it into halves.
