You can prove that to triangles are congruent with SSS, then use CPCTC to prove that two corresponding angles of those triangles are congruent.

When do you use CPCTC?

You can only use CPCTC after you prove the 2 triangles congruent.


How do you find a triangle congruent by cpctc?

A triangle if not found congruent by CPCTC as CPCTC only applies to triangles proven to be congruent. If triangle ABC is congruent to triangle DEF because they have the same side lengths (SSS) then we know Angle ABC (angle B) is congruent to Angle DEF (Angle E)


When and why do you use CPCTC?

CPCTC, which stands for "Corresponding Parts of Congruent Triangles are Congruent," is used after proving that two triangles are congruent through methods like SSS, ASA, or AAS. Once congruence is established, CPCTC allows us to conclude that corresponding sides and angles of the triangles are also congruent. This principle is essential in geometric proofs and problem-solving to derive further relationships and properties based on triangle congruence.


What does CPCTC represent and when would you use it?

CPCTC represents Corresponding Parts of Congruent Triangles are Congruent. You would use this in Triangle Proofs.


When can I use CPCTC?

You can use it to corresponding parts of a trianglr


What are reasons used in the proof that the angle-bisectors construction can be used to bisect any angle?

All of the radii of a circle are congruent CPCTC sss triangle congruence postulate


Why would you use CPCTC?

Once you have shown that two triangles are congruent you can use CPCTC (corresponding parts of congruent triangles are congruent) to show the congruence of the remaining sides and angles.


What is the scale factor of congruent figures?

In gemortry, CPCTC is the abbreviation of a therom involving congrugent triangles. CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent. CPCTC states that if two or more triangles are proven congruent by: ASA, AAS, SSS, HL, or SAS, then all of their corresponding parts are congruent as well.Ifthen the following conditions are true:A related theorem is CPCFC, in which triangles is replaced with figures so that the theorem applies to any polygon or polyhedrogen.


Why doesn't CPCTC guarantee that triangles are equilateral?

CPCTC, or Corresponding Parts of Congruent Triangles are Congruent, applies only to triangles that have already been established as congruent through specific criteria (like SSS, SAS, ASA, etc.). This means that while the corresponding angles and sides of two congruent triangles are equal, it does not imply that all triangles involved are equilateral. Congruence only guarantees that the triangles have the same shape and size, which can include various types, not just equilateral triangles. Thus, CPCTC does not extend to making a claim about the nature of the triangles beyond their congruence.


If abcadc which is true by CPCTC?

In the context of CPCTC (Corresponding Parts of Congruent Triangles are Congruent), if triangles ABC and ADC are congruent due to some criteria (like SSS, SAS, ASA, etc.), then corresponding parts such as side AB and side AD, as well as angle A, would be congruent. Therefore, if triangles ABC and ADC are congruent, it can be concluded that AB = AD and ∠A = ∠A. Thus, any corresponding parts of the triangles would be equal.


what- the image of a triangle after a translation is shown. fill in the blank with a congruence postulate. use SSS?

SSS


what- If you are given or can prove that two triangles are congruent, then you may use CPCTC to prove that the angles or sides are?

congruent
