Question

1. what can you say about the lengths of the segments formed if a line perpendicular to the base of an isosceles triangle bisects the vertex angle? they are equal no clear relation can be defined they are different one is half of the other

Explanation:

In an isosceles triangle, the line perpendicular to the base and bisecting the vertex angle is also the median and altitude (by the properties of isosceles triangles). This line divides the base into two segments. By the Angle - Side - Angle (ASA) congruence criterion, the two triangles formed are congruent, so the segments of the base (formed by this perpendicular line) are equal in length.

Answer:

A. They are equal
