Corresponding Sides
If △ABC ≅ △DEF, which side corresponds to AB?
DE
If △ABC ≅ △DEF, which angle corresponds to ∠A?
∠D
Two triangles have exactly the same shape and size. What word describes them?
congruent
Name one rigid motion that can map a figure onto a congruent figure.
a translation, rotation, or reflection?
If △ABC ≅ △DEF, which side corresponds to BC?
EF
If △ABC ≅ △DEF, which angle corresponds to ∠C?
∠F
If A ↔ D, B ↔ E, and C ↔ F, complete the statement: △ABC ≅ ___.
△DEF
If △ABC ≅ △DEF and AB = 11 cm, what is DE?
11 cm
If △XYZ ≅ △PQR, which side corresponds to XZ?
PR
If △XYZ ≅ △PQR and ∠Y = 65°, what is ∠Q?
65°
If P ↔ X, Q ↔ Y, and R ↔ Z, write a congruence statement.
△PQR ≅ △XYZ
If △ABC ≅ △DEF, ∠A = 50° and ∠B = 60°, what is ∠F?
70°
∠C = 70°, and C corresponds to F.
If AB = 8 cm and △ABC ≅ △DEF, how long is DE?
8 cm
If △LMN ≅ △RST, which angle corresponds to ∠M?
∠S
△ABC ≅ △DEF. Is △BCA ≅ △EFD also a correct statement?
Yes! The corresponding vertices remain matched:
B ↔ E, C ↔ F, and A ↔ D.
If △JKL ≅ △MNP, which side corresponds to KL?
NP
If △LMN ≅ △RST, and LM = 7, MN = 9, and LN = 12, what is ST?
9 units. MN corresponds to ST.
If ∠A = 45° and ∠B = 75° in △ABC, and △ABC ≅ △DEF, what is ∠F?
60°.
∠C = 180° − 45° − 75° = 60°,
and ∠C corresponds to ∠F.
△ABC ≅ △DEF. A student writes △ABC ≅ △DFE. What is the mistake?
The order is incorrect. B corresponds to E and C corresponds to F, so the correct statement is △ABC ≅ △DEF.
△RST ≅ △UVW. If RS = 6, ST = 10, RT = 8, and UV = 6, what are VW and UW?
VW = 10 and UW = 8.
