A farmer wants to build two triangular garden beds. The first triangle has sides measuring {a}m, {b}m, and {c}m. The second triangle also needs to be congruent with the first one using the SSS theorem. What should the side lengths of the second triangle be?

Which pair of triangles is congruent by Side-Angle-Side (SAS)?
Triangle A: Sides 5 cm and 7 cm with included angle 60°; Triangle B: Sides 5 cm and 7 cm with included angle 60°.
Triangle C: Sides 6 cm and 8 cm with non-included angle 45°; Triangle D: Sides 6 cm and 8 cm with non-included angle 45°.
If two triangles have two equal sides and an equal included angle, what congruence theorem guarantees that they are congruent?
ASA
SSS
SAS
Which pairs of triangles can be proven congruent using the Side-Side-Side (SSS) congruence theorem?
Triangle E: Sides 5 cm, 5 cm, and 7 cm; Triangle F: Sides 5 cm, 5 cm, and 7 cm.
Triangle G: Sides 6 cm, 8 cm, and 10 cm; Triangle H: Sides 6 cm, 9 cm, and 10 cm.
If Triangle A and Triangle B have angles {angle3}° and {angle4}°, and a non-included side of {s}cm, can we say they are congruent by the AAS theorem?
Yes, AAS theorem applies.
No, AAS cannot be used here.
For two right triangles, if the hypotenuse is {hypotenuse}cm and one leg is {leg}cm, they are congruent by which theorem?
