Question

triangle ABC similar to triangle DEF and angle A 80 dregees,line segment AB 6cm,AC 5cm,angle A=angle D and DE is a congruent to AB find line segment DE and line segment DF ​

Answer 1

Step-by-step explanation:

For triangle to be congruent SAS(Side angle Side) axiom we need to have two equal sides and the included angle same.

In ΔABC and ΔDFE

We have AB=DF

and ∠A=∠D

But ∠A is formed by the two sides AB and AC of ΔABC

But ∠D is formed by the two sides DE and DF of ΔDFE

So we need AC=DE for the two triangles to be congruent.
