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.
'corresponding parts of congruent triangles are congruent'
CPCTC is an acronym for the phrase 'corresponding parts of congruent triangles are congruent' It means that once we know that two triangles are congruent, we know that all corresponding sides and angles are congruent.
If two triangles are proven to be congruent, then corresponding parts of those triangles are congruent as well. This principle is known as CPCTC, which stands for "Corresponding Parts of Congruent Triangles are Congruent." Therefore, you can conclude that the corresponding angles and sides of the two triangles are equal in measure.

A quadrilateral is a parallelogram if one pair of opposite sides are equal and parallel Let ABCD be a quadrilateral in which ABCD and AB=CD, where means parallel to. Construct line AC and create triangles ABC and ADC. Now, in triangles ABC and ADC, AB=CD (given) AC = AC (common side) Angle BAC=Angle ACD (corresponding parts of corresponding triangles or CPCTC) Triangle ABC is congruent to triangle CDA by Side Angle Side Angle BCA =Angle DAC by CPCTC And since these are alternate angles, ADBC. Thus in the quadrilateral ABCD, ABCD and ADBC. We conclude ABCD is a parallelogram. var content_characters_counter = '1032';
You can only use CPCTC after you prove the 2 triangles congruent.
CPCTC represents Corresponding Parts of Congruent Triangles are Congruent. You would use this in Triangle Proofs.
You can use it to corresponding parts of a trianglr
You can prove that to triangles are congruent with SSS, then use CPCTC to prove that two corresponding angles of those triangles are congruent.
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.

Before using Corresponding Parts of a Congruent Triangle are Congruent theorem (CPCTC) in a geometric proof, you must first prove that there is a congruent triangles. This method can be used for proving polygons and geometrical triangles.
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)
