Use the information given to draw a conclusion based on the state property or definition.

Substitution property of equality geometry. In this video were going to talk about the transitive property the substitution property and also vertical angles so heres the general idea of the transitive property if angles are congruent to the same angle then theyre congruent to each other so for instance lets say if angle 1 is congruent to angle 2 and if angle 3 is congruent to angle 2 then we can make the statement that angle 1 is congruent to. Name the appropriate property. If you ever plug a value in for a variable into an expression or equation youre using the Substitution Property of Equality.

Mwmxmz180 Substitution property of equality. 12 Given M is the midpoint of. X 5 7 2x 1 4 5 27 1 4 Example Use Properties of Equality and Congruence A M B STUDY TIP In geometry you can use properties of equality that you learned in algebra.

X y 3 Given 2. Reflexive symmetric addition subtraction multiplication division substitution and. If two geometric objects segments angles triangles or whatever are congruent and you have a statement involving one of them you can pull the switcheroo and replace the one with the other.

The substitution property of equality states that for any real numbers a and b if a b then a can be substituted for b. Transitive Property of Equality - Math Help Students learn the following properties of equality. Caproiu Hall 2000.

2 Substitution Property. This geometry video tutorial provides a basic introduction into the transitive property of congruence and the substitution property of equality. X 13 3 Substitution property 12 4.

Substitution Property Substituting a number for a variable in an equation produces an equivalent equation. X -10 Combining like terms. Mxmy Vertical angles are equal in measure.

If Johns height Marys height then Johns height 5 Marys height 5 If 8 8 then 8 3 8 3 If 2y 4 10 then 2y 4 - 4 10 - 4 Multiplication property. Mwmxmz The exterior angle of a triangle equals the sum of the two opposite interior angles. If x y then x z y z.

In simple words ab implies that ba therefore in any algebraic expression or equation we can replace any a with b or any b with a. Given the diagram to the right prove that mwmymz. Mwmymz Substitution property of equality.

There are many examples of this but we can use basic arithmetic operations to demonstrate this property. X 13 - 13 3 - 13 Subtraction property of equality 5. Y 13 Given 3.

At this point weve already simplified this to something very straightforward so well finish the proof now. The substitution property of equality states that for any quantities or expressions if a b then substituting a or b for the other in a given expression will yield the same result. This property allows you to substitute quantities for each other into an expression as long as those quantities are equal.

Created by Varaz and Vasag Bozoghlanian. 6 Addition Property of Equality. Math Study Strategies Learning Center The Reflexive Property a a The Symmetric Property If ab then ba The Transitive Property If ab and bc then ac The Substitution Property.

If x y then x z y z Example. Properties of Equality For more information about this and other math topics come to the Math Lab 722-6300 x 6232. Note that you will not be able to find the term switcheroo in your geometry glossary.

Use the definition of an. 4 Addition Property of Equality. Since JNM and HMN are same-side interior angles the measure of JNM plus the measure of HMN equals 180.
