PLEASE HELP! Complete each congruency statement and name the rule that is used. If you cannot show the triangles are congruent from the given information, leave the triangle's name blank and write "CNBD" for "Cannot be determined" in place of the rule. M is the midpoint of line CI. ΔCAM ≅ Δ_ by _

In the situation where segment is perpendicular to segment , such that is the perpendicular bisector to segment we have the following two column proof;

Statement                             Reason

M is the midpoint of        Given

≅                              Definition of midpoint

≅                            Reflexive property

∠CMA = ∠IMA = 90°              Definition of perpendicular bisector

ΔCAM ≅ ΔIAM                      By the Side-Angle-Side (SAS) rule of congruency

However, where the segment is not be assumed as perpendicular to segment , then CNBD
