Reflection: Math Success

Take Note: Match each item on the left with the property it demonstrates on the right.

Assume that a, b, and c are real numbers, that a = b, and that c ≠ 0.
If 7 = a, then a = 7.
Addition Property of Equality
b = b
Subtraction Property of Equality
a - 17 = b - 17
Multiplication Property of Equality
5(a - b) = 5a - 5b
Division Property of Equality
a ÷ 4 = b ÷ 4
Reflexive Property of Equality
-3b = -3a
Symmetric Property of Equality
a + 5 = b + 5
Transitive Property of Equality
If a = b and b = 24, then a = 24.
Substitution Property of Equality
If c = 10, then 10 can replace c in any expression.
Distributive Property
Take Note: Categorize each item on the left with the property it demonstrates on the right.
\angle{1} \cong \angle{1}
\overline{ST} \cong \overline{ST}
If \angle{B} \cong \angle{M}, then \angle{M} \cong \angle{B}.
If \overline{PR} \cong \overline{TS} and \overline{TS} \cong \overline{ML}, then \overline{PR} \cong \overline{ML}.
Reflexive Property of Congruence
Symmetric Property of Congruence
Transitive Property of Congruence

Vocabulary Review: Classify each item on the left.
2(a-5)^2
3x+2=4
9<x-2
5+3^4
Equation
Not and equation
Use Your Vocabulary: Match each equation in the left column with the property you would use to justify it on the right.
2\cdot (5\cdot x)=(2 \cdot 5) \cdot x
Commutative Property of Addition
3+7=7+3
Commutative Property of Multiplication
1+(9+53)=(1+9)+53
Associative Property of Multiplication
12(4)=4(12)
Associative Property of Addition
