Question

in figure ab =ac and ad perpendicular to bc​

Answer 1

Answer:

Yes they are congruent

Step-by-step explanation:

First Ab =AS (corresponding sides are equal)

2nd Angle at d is same for both triangle 90 degrees

3rd As AD is Perpendicular to BC so BD=DC (corresponding sides are equal again)

So 2 sides and one angle are equal

So triangles must be congruent by hypotenuse leg theorem and SAS postulate.
