Answer:
Segment AB || Segment CD
Step-by-step explanation:
Two lines are said to be parallel (||) if they do not meet, even when extended to infinity.
Given: <1 ≅ <3, ΔACD is an isosceles triangle.
Proof: Segment AB || Segment CD
From the diagram given,
AC ≅ AD (side property of isosceles triangle)
<3 = <4 (base angle property of an isosceles triangle)
<1 = <4 (alternate angle property)
Therefore, segment AB is parallel to segment CD.
