ABCD is a square Triangle DEF is equilateral Triangle ADE is isosceles AD= AE CDF is a straight line Show all your steps, calcutate the size of angle AEF

90 degrees

Step-by-step explanation:

Triangle DEF is equilateral, therefore:

Angle DFE=Angle DEF =Angle EDF

ABCD is a square, therefore:

In the straight line CF

Recall that triangle ADE is an Isosceles triangle; therefore:

(Base angles of an Isosceles Triangle)

We then have:
