Question

complete the conjecture about the relationship between two intersecting lines that form four congruent angles. the lines are select choice.

Explanation:

Step1: Recall Angle Properties

When two lines intersect, the sum of all four angles is \(360^\circ\). If the four angles are congruent, let each angle be \(x\). Then \(4x = 360^\circ\), so \(x = 90^\circ\).

Step2: Identify Line Relationship

Lines that intersect at \(90^\circ\) angles are perpendicular. So the lines are perpendicular.

Answer:

perpendicular
