Question

Figure abcd is a square. Find the measure of < ABE

Answer 1

Answer:

45 degrees

Step-by-step explanation:

Because the shape is a square, all of the sides are equal and all of the angles are 90 degrees. From there you simply divide  90 by 2.

Answer 2

Answer:

∠ ABE = 45°

Step-by-step explanation:

The diagonals of a square bisect the angles, thus

∠ ABC = 90°, so

∠ ABE = 0.5 × 90° = 45°
