Question

from this given statement, select the definition, property, postulate, or theorem that justifies the prove statement. given: parallelogram aeio prove: ∠a ≅ ∠i, ∠e ≅ ∠o

Explanation:

In a parallelogram, one of the fundamental properties is that opposite angles are congruent. Here, in parallelogram \( AEIO \), \( \angle A \) and \( \angle I \) are opposite angles, and \( \angle E \) and \( \angle O \) are opposite angles.

Answer:

The property that justifies the statement \( \angle A\cong\angle I,\angle E\cong\angle O \) is the "Opposite angles of a parallelogram are congruent" property.
