Answer 1

∠AEF  =  90° abcd is a square ,  triangle def is an equilateral triangle , ade is isosceles with ad=ae CDF is a straight line

Step-by-step explanation:

ABCD is Square

CDF is a straight line

∠ADF = 90°

DEF is an Equilateral Triangle

∠FDE = 60°

=> ∠ADE = 90° - 60° = 30°

AD = AE

=> ∠AED = 30°

∠DEF = 60°   ( equilateral triangle)

∠AEF  = ∠AED + ∠DEF

=> ∠AEF  =  30° + 60°

=> ∠AEF  =  90°
