Question

4.5 assignment
tell whether you can use the given information to determine whether △abc ≅ △def △abc ≅ △def △abc ≅ △def △abc ≅ △def.if so, state the postulate or theorem you would use.
∠b ≅ ∠e
∠c ≅ ∠f
\overline{ac} ≅ \overline{df}
(hint: draw a picture...)
yes, sss
yes, sas
yes, hl
yes, aas
yes, asa
no

Explanation:

Step1: Recall triangle congruence theorems

• SSS (Side - Side - Side): All three sides of one triangle are equal to the corresponding sides of another triangle.
• SAS (Side - Angle - Side): Two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.
• HL (Hypotenuse - Leg): For right - angled triangles, the hypotenuse and one leg are equal.
• AAS (Angle - Angle - Side): Two angles and a non - included side of one triangle are equal to the corresponding parts of another triangle.
• ASA (Angle - Side - Angle): Two angles and the included side of one triangle are equal to the corresponding parts of another triangle.

Step2: Analyze the given information

We are given \(\angle B\cong\angle E\), \(\angle C\cong\angle F\), and \(\overline{AC}\cong\overline{DF}\). The non - included side (\(\overline{AC}\) and \(\overline{DF}\)) is equal, and two pairs of angles are equal.

Answer:

Yes, AAS
