Question

# In the figure, AF is perpendicular to BC and AF is the angle bisector of , then state the rule used for the congruence of Δ DAF an ΔEAF.

Hint:

### Find the congruence rule from the figure provided.

## The correct answer is: ASA congruence rule

### Consider ΔDAF and ΔEAF

(Since AF is perpendicular to BC)

AF = AF (Common side)

(AF is angle bisector of )

So, by ASA congruence rule we have

ΔDAF⩭ ΔEAF
