All angles in a rectangle Are 90°

∴∠B=90°
∠OBC=90°/2            (Because of the angular bisecter which divides an 
                                  angle into half)
                                  
∠C=90°
∠OCB=90°/2
-----------------------------------------------
IN ΔBOC
∠OCB=∠OBC=90°
∴Base angles of the triangle are equal
so the TRIANGLE is an ISOCELES TRIANGLE.
