Answer:
45°
Step-by-step explanation:
Quadrilateral LEAH at the picture is a square. Find m∠ALE
Solution:
Quadrilateral LEAH is a square and a square is a rectangle. Therefore, m∠HLE= 90.
But each diagonal of a square bisects a pair of opposite angles. Hence, m∠ALE= 1/2 m∠HLE
Substitute 90 for m∠HLE, m∠ALE= 1/2(90)= 45
Therefore, the measure of ∠ALE is 45°
