Question

In angle ACB and EFD , angle f and angle c =90 , and EF =AC , then find the third condition to prove the congruence of the two triangles using the RHS criteria
​

Answer 1

Answer:

For triangle to be congruent by SAS axiom two of the sides and the included angle of the triangles must be equal.

Given AB=DF and ∠A=∠D

No for △ABC≅△DFE by SAS axiom we need AC=DE

Answer 2

Answer:

Correct option is

D

∠A=∠D,∠B=∠E,∠C=∠F

If triangles are congruent then their corresponding angles are equal

Here △ABC≅△DEF

⇒∠A=∠D,∠B=∠E,∠C=∠F
