The distance between points A and Z is same as the distance between X and Z.
What are congruent triangles?
"Two triangles are said to be congruent if and only if measure of corresponding sides and angles of one triangle is equal to other triangle."
Theorem used
Angle side Angle(ASA)
When two angles and included side of one triangle is congruent to two angles and included sides of other triangle then triangles are said to be congruent.
According to the question,
Given,
In ΔYZA and ΔYZX,
∠YZA ≅ ∠YZX (each 90°)
∠XYZ ≅ ∠AYZ
YZ ≅YZ (common side)
By ASA theorem of triangles we get,
ΔYZA ≅ΔYZX
Therefore, distance between given points are congruent.
[tex]\bar{AZ} =\bar{XZ}[/tex]
Hence, Option(C) is the correct answer.
