Question

If triangle ABC is congruent to triangle XYZ, then which of the following is congruent to CA? A. AB. B. XY C. YZ D. ZX

Answer 1

When we point out the congruence of triangles ABC and XYZ,

which we denote by
`ABC\cong XYZ`, the order of the letters is very important.

What we understand from
`ABC\cong XYZ` is :


`\angle A \cong \angle X\\\\\angle B \cong \angle Y\\\\\angle C \cong \angle Z`

and:


`AB \cong XY\\\\BC \cong YZ\\\\ AC \cong XZ`

Following this logic of preserving the order precisely, side CA is congruent to ZX


Answer: D) ZX
