The correct option is;
The sum of angles A and B are supplementary to angle C
Step-by-step explanation:
The statements are analysed as follows
1. Angle A is congruent to itself reflective property
Which shows that ΔABC and ΔADE have a common and equal angle
2. Segment ED and CB are parallel
From the transversal line passing EB and CB which shows that the angles ∠ADE and ∠ABC are equal and also ∠AED and ∠ACB are equal
The statement is used to prove similarity between the ΔABC and ΔADE
3. The sum of angles A and B are supplementary to angle C
The above statements relates to only ΔABC and i does not show similarity between ΔABC and ΔADE.
