Expert Answer
angle DAC and angle EBC are equal and supplementary
angle DAC = angle EBC = 90o
hence in triangle DAC and triangle EBC
DC and CB is hypotenuse
DC=CB....C is mid point
Also
AC=BC...sides of equilateral tringle
Hence triangle DAC is congruent to triangle EBC by Right hypotenuse side theorem
