Congruence & Triangles

If ∆DEF ≅ ∆ACB, then the part of ∆ACB that corresponds to angle F is :

• Angle A

• Angle B

• Angle C

• None of these

Under a given correspondence, two triangles are congruent if the three sides of the first are equal to the three corresponding sides of the other. The above is known as :

• SSS congruence of two triangles.

• SAS congruence of two triangles.

• ASA congruence of two triangles.

• None of these.

Under a given correspondence, two triangles are congruent if two sides and the angle included between them of the first are equal to the corresponding sides and the angle included between them of the other triangle. The above is known as :
