If M2220a = M2220b And M2220a + M2220c = 2220d, Then, M2220b + M2220c = 2220d., Which Property Is Shown?, Reflexive Property, Substitution Property, S

If m∠A = m∠B and m∠A + m∠C = ∠D, then

m∠B + m∠C = ∠D.

Which property is shown?

reflexive property
substitution property
symmetric property
transitive property

 

Answer:

Substitution Property

Step-by-step explanation:

It is the substitution property.

Since it states that for every real number x or y, if x = y, then x and y may be substituted for each other in any equation.

Example:

If x = y + 2, then x can be substituted in place of (y + 2) in the equation, 3(y + 2) + x = 12, to get 3x + x = 12.

Hope it helps!
