Question

It is given that ∆ ABC ≅ ∆FDE and AB = 6.5cm, ⦟B=40°, ⦟A=80°
find F D and ⦟E

Answer 1

Answer:

Given that ΔABC is congruent to ΔFDE

so, AB = FD (Cpct)

FD = 6.5cm

angle A + angle B + angle C = 180°

angle c = 180° - (80° + 40° )

= 180° - 120°

= 60°

now angle C = angle E (Cpct)

so, angle E = 60°
