Question

Ques 3. Triangle AABC is congruent to
triangle A DFE. If angle A= 40°, angle C =
80°. The value of angle F is *

Answer 1

Answer:

F = 60°

Step-by-step explanation:

it is very simple

sum of three angles 180°

so add angle a and angle c

40+80 = 120

as sum of 3 angles 180°

so, 180 - 120 = 60°

∴ a=40°,c=80°,f=60°
