Answer:
pls view this image
Step-by-step explanation:
since according to diagram
AE is bisector of angle BAC and EC is bisector of angle DCA
AND sum of Angles (EAC+ECA)=90°
THEREFORE sum of ANGLES(BAC+DCA)
=180°
HENCE PROVED
this would not be the case in intersecting lines
thus these are parallel lines
hope it helps
pls mark it as brainliest answer
give it a thumbs up if u like the solution
