CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.' It is a principle used to prove that corresponding angles and sides of congruent triangles are equal.
2.
FLASHCARD QUESTION
Front
If triangle ABC is similar to triangle DEF, how do you find the corresponding angles?
Back
The corresponding angles can be found by matching the vertices of the triangles. For example, if A corresponds to D, then angle A is equal to angle D.
3.
FLASHCARD QUESTION
Front
What is the relationship between corresponding sides of similar triangles?
Back
The lengths of corresponding sides of similar triangles are proportional. If triangle ABC is similar to triangle DEF, then \( \frac{AB}{DE} = \frac{BC}{EF} = \frac{AC}{DF} \).
4.
FLASHCARD QUESTION
Front
How do you identify corresponding angles in similar triangles?
Back
Corresponding angles are the angles that are in the same relative position in each triangle. For example, if angle A corresponds to angle D, then they are equal.
5.
