The statement - The measure of angle x is always less than the measure of angle Y - is the true statement
How to determine the true statement
To determine the true statement, let's consider the given condition: side XZ is longer than side YZ in triangle XYZ. We want to evaluate the statement:
The measure of angle X is always less than the measure of angle Y
If side XZ is longer than side YZ, it implies that angle X is opposite the longer side and angle Y is opposite the shorter side.
In a triangle, the angle opposite the longer side is always larger than the angle opposite the shorter side.
This is known as the angle-side relationship in triangles.
