What is the measure of ZABD? What is the reason?56 degrees, isosceles triangle theorem56 degrees, equilateral triangle theorem62 degrees, isosceles triangle theoremB62 degrees, isosceles triangle theorem62°DA

Explanation:
The sum of angles in triangle ABD is 180 degrees
The two short marks represent two sides are equal. As a result, the two base angles are also equal.
This properties represent an isosceles triangle
Since the base angle are the same,
