Question

in the given figure, which line or segments are parallel? justify your answer. choose the correct answer below.
a. garbled by the converse of the alternate interior angles theorem
b. garbled by the converse of the same side interior angles postulate
c. garbled by the converse of the alternate exterior angles theorem
d. garbled by the converse of the corresponding angles theorem

Explanation:

To determine parallel lines, we analyze each option:

• Option A: If using the Converse of Alternate Interior Angles Theorem (if alternate interior angles are equal, lines are parallel), checking the diagram (assuming \( \overline{IJ} \) and \( \overline{GH} \) with transversal, alternate interior angles equal), this holds.
• Option B: Same - Side Interior Angles Postulate's converse requires same - side interior angles supplementary, not indicated here.
• Option C: Alternate Exterior Angles Theorem's converse doesn't apply to \( \overline{DK} \) and \( \overline{GH} \) as per diagram.
• Option D: Corresponding Angles Theorem's converse for \( \overline{OK} \) and \( \overline{ON} \) is incorrect as they seem perpendicular (given right angle symbol), not parallel.

So the correct answer is A.

Answer:

A. \( \overline{IJ} \parallel \overline{GH} \) by the Converse of the Alternate Interior Angles Theorem
