Since a = c, we can substitute any number to them.
Let's say that a = c = 0. a and c is now equal to 0. So, b = 180 and d = 180.
We can rewrite that to b = 180 = d. This means that if a is equal to c, b will also always be equal to d. (You can substitute any values to a and c as long as they're equal and you will know that b = d)

Answer:
b = d
Step-by-step explanation:
