Proving Triangle Congruent SSS SAS CPCTC

All of the following prove triangles congruent except

• SSS

• SAS

• CPCTC

• HL

What will the last "reason" of this proof be?

• Definition of Midpoint

• Definition of Angle Bisector

• CPCTC

• Reflexive

What additional information can we conclude from the given and why?

• ∠ADB and ∠ADC are right angles because AD goes straight down.

• ∠B≅∠C because the triangle is isosceles
