Given AC-3, 1), B(1, 4) and C(4, 0): a. Show that triangle ABC is isosceles.

b. Find the midpoint X of line segment AC.

c. Find the equations of any lines of symmetry of triangle ABC.

Two rigid transformations are used to map abc to qrs. the first is a translation of vertex b to vertex r. what is the second transformation? a reflection across the line containing ab a rotation about point b a reflection across the line containing cb a rotation about point c
