Question

in a square. ABE is an isosceles triangle where AB = BE. Find ZAED.
13. BCDE is a square. AB
60​

Answer 1

Answer:

ABCD is a square so all angle are of 90°

and AC is a straight line so

angle ABE+ angle CBE = 180°

angle ABE= 180°-90°

angle ABE=90°

and ABE IS a isosceles triangle in which AB=BE

so angle E= angle A ( angle opposite to equal sides are equal)

in Triangle ABE

angle A+ angle ABE + angle E=180°

angle A + angle A = 180°- angle ABE. (angle E = angle A)

2 angle A = 180°-90°

angle A= 90°÷2

angle A = 45°

so angle E = 45°

Answer 2

Answer:

135°

Step-by-step explanation:

BCDE is a square and all angles are of 90°

angle ABE is right angle

angle AEB = 90°/2 = 45

angle AED = angle AEB + angle BED

angle AED = 45° +90°

angle AED = 135°
