State what additional information is required in order to know that the triangles are congruent. Be sure to be specific with your answer. Do not simply write "an angle is needed or a side is needed."Be specific. Be mindful, order matters. For example, there should be an angle marking on angle X and angle Y. Angle Y must be congruent to Angle X to show that the triangles are congruent by SAS. Another example, side AB and side CD should have tick marks. Side AB and side CD must be congruent to show that triangles are congruent by SSS.
