Which statements are true? select two options. δabc is-congruent-to δbxc δaxc ~ δcxb δbcx is-congruent-to δacx δacb ~ δaxc δcxa
aliina [53]

Based on the properties of similar triangles, the two true statements are:

  1. ΔAXC ≅ ΔCXB.
  2. ΔACB ≅ ΔAXC.

<h3>The properties of similar triangles.</h3>

In Mathematics, two (2) triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.

Based on the properties of similar triangles, we have the following points:

  • ∠A in ΔAXC matches ∠A in ΔABC and ∠C in ΔCXB.
  • ∠C in ΔAXC matches ∠B in ΔABC and ∠B in ΔCXB.
  • ∠X in ΔAXC matches ∠C in ΔABC and ∠X in ΔCXB.

In this scenario, we can can logically deduce that the two true statements are:

  1. ΔAXC is congruent to ΔCXB (ΔAXC ≅ ΔCXB).
  2. ΔACB is congruent to ΔAXC (ΔACB ≅ ΔAXC).
