Question

it is given that triangle abc = triangle fde and ab is 4 cm angle b 40 degree and e is 60 degree​

Answer 1

Answer:

∠a=80 degrees and FD=4cm

Step-by-step explanation:

ABC ≅ FDE

AB= 4cm

∠b=40 degrees

∠e=60 degrees

Since triangles are congruent:

AB=FD=4cm

∠b=∠d=40 degrees

∠e=∠c=60 degrees

∠a=∠f

Sum of angles of a triangle= 180 degree

180=60+40+x

x=180-60-40

x=80 degree

∴∠a=∠f=80 degree

Thus we can say that the following conditions about the triangle {given in the answer}
