# The Transitive Property of Congruence in Geometry

In geometry, two figures are congruent if they have the same size and shape. This means that all corresponding sides and angles are equal. The transitive property of congruence states that if two figures are congruent to a third figure, then they are also congruent to each other. In other words, if Figure A is congruent to Figure B, and Figure B is congruent to Figure C, then Figure A is also congruent to Figure C.

The transitive property of congruence is represented using the symbol "≅". So, the statement "Figure A is congruent to Figure B" would be written as "Figure A ≅ Figure B".

To better understand the transitive property of congruence, let's look at an example.

Example:

Given:?LMN≅?GHI Prove: ?LMN≅?HGI Statement Reason 1. ?LMN≅?GHI Given 2. LM≅GH CPCTC 3. LN≅GI CPCTC 4. ?LMN≅?HGI Transitive Property 5. m∠LNM≅m∠HGI SAS 6. m∠MLN≅m∠IHG SAS 7. m∠NLM≅m∠GHI SAS 8. ?LMN≅?HGI HL 9. ?LMN≅?GII CPCTC 10. MN≅GI CPCTC 11. ?LMN≅?HGI Transitive Property 12. ?LMN≅?GHI Reflexive Property 13. ?LMN≅?GHI Transitive Property 14. m∠LNM=m∠GHI Angle-Angle-Side 15. m LGHM=m HFIG Angle-Angle-Side 16 LGM=HF Side-Side-Side 17 GM=FG Side-Side-Side 18 MN=GI Side-Side-Side 19 LMFN=HIGI Side Angle Side 20 FM=EG Side Side Side 21 FN=EI SSS 22 ∴ ΔLMN ≅ ΔHGI Proven // 22 steps in 2 columns

As you can see from the example above, if Figures A, B, and C are all congruent to each other, then it can be proven using the transitive property of congruence.

The transitive property of congruence is an important concept in geometry that states that if two figures are congruent to a third figure, then they are also congruent to each other. This principle can be represented using the symbol "≅" and is often used to prove whether or not two figures are Congruent to each other by transferring properties between Congruent figures until the desired result has been achieved.

## FAQ

### What is transitive property of congruence example?

The transitive property of congruence states that if two triangles are congruent, then their corresponding sides and angles are also congruent. For example, if Triangle ABC is congruent to Triangle DEF, then:Side AB is congruent to Side DE . Side BC is congruent to Side EF. Side AC is congruent to Side DF. Angle A is congruent to Angle D. Angle B is congruent to Angle E. Angle C is congruent to Angle F.

### What is an example of transitive property in geometry?

The transitive property of congruence states that if two triangles are congruent, then their corresponding sides and angles are also congruent. For example, if Triangle ABC is congruent to Triangle DEF, then:Side AB is congruent to Side DE. Side BC is congruent to Side EF. Side AC is congruent to Side DF. Angle A is congruent to Angle D. Angle B is congruent to Angle E. Angle C is congruent to Angle F.

### How do you use the transitive property?

The transitive property can be used to prove geometric theorems. For example, the theorem that "the sides of a triangle are proportional to the sines of the corresponding angles" can be proved using the transitive property. Let ABC be a triangle with sides a, b, and c. Let A', B', and C' be the angles opposite to sides a, b, and c respectively. Then, by the transitive property, if a:A' = b:B' and b:B' = c:C', then a:A' = c:C'. Therefore, the sides of a triangle are proportional to the sines of the corresponding angles.

### How do you prove the transitive property of congruence?

The transitive property of congruence can be proved using the SSS (Side-Side-Side) Congruence Theorem. This theorem states that if all three sides of two triangles are congruent, then the triangles are congruence. Therefore, if Triangle ABC is congruent to Triangle DEF and Triangle DEF is congruent to Triangle GHI, then Triangle ABC is congruent to Triangle GHI by the transitive property.

What is the transitive property of equality?The transitive property of equality states that if a=b and

b=c, then a=c. This property is often used to solve algebraic equations. For example, if x+3=5 and 3+4=7, then by the transitive property of equality, x+3=7. Therefore, x=4.

### What is transitive property?

The transitive property is a mathematical principle that states that if A=B and B=C, then A=C. This property can be applied to a variety of mathematical concepts, including equality, congruence, and order. The transitive property is often used to solve algebraic equations. For example, if x+3=5 and 3+4=7, then by the transitive property of equality, x+3=7. Therefore, x=4.

### How do you use the transitive property in geometry?

The transitive property can be used to prove geometric theorems. For example, the theorem that "the sides of a triangle are proportional transitive property can be used to prove geometric theorems. For example, the theorem that "the sides of a triangle are proportional to the sines of the corresponding angles" can be proved using the transitive property.
