Which property is shown?
if m∠abc = m∠cbd, then m∠cbd = m∠abc
reflexive property
substitution property
symmetric property
transitive property

The correct answer is:

symmetric property .

Explanation:

The symmetric property states that if two things are equal, we can "flip" them around the equals sign. Algebraically, this is written as

If a=b, then b=a.

This is true of our angles as well; therefore this is the symmetric property.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
