If two triangles are congruent, the following statements must be true: their corresponding sides are equal in length, and their corresponding angles are equal in measure. Additionally, the triangles can be superimposed on each other, meaning they occupy the same space when aligned. This congruence indicates that all geometric properties of the triangles are identical.
If triangles ABC and DEF are congruent (ABC ≅ DEF), then corresponding parts of the triangles are congruent by the principle of CPCTC (Corresponding Parts of Congruent Triangles are Congruent). This means that segments AB ≅ DE, BC ≅ EF, and AC ≅ DF, as well as angles ∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F. All these congruences must be true if the triangles are indeed congruent.

In a square WXYZ, the following statements must be true: all sides are equal in length, each angle measures 90 degrees, and the diagonals bisect each other at right angles and are equal in length. Additionally, the diagonals also divide the square into two congruent triangles.
To determine which congruences are true by CPCTC (Corresponding Parts of Congruent Triangles are Congruent), we need specific information about the triangles involved. If triangles ABC and DEF are congruent, then corresponding sides and angles, such as AB ≅ DE, BC ≅ EF, AC ≅ DF, and ∠A ≅ ∠D, ∠B ≅ ∠E, ∠C ≅ ∠F, would all hold true. Please provide more details about the triangles or congruences in question for a precise answer.
To prove two triangles congruent by the Hypotenuse-Leg (HL) theorem, you need to know that both triangles are right triangles. Additionally, you must establish that the lengths of their hypotenuses are equal and that one pair of corresponding legs is also equal in length. With this information, you can confidently apply the HL theorem to conclude that the triangles are congruent.

If you don't tell us what the statements are, we can't tell you which ones could be false. The ones that could be false are the ones that state something that doesn't apply to congruent triangles.

No, it is not correct.If lmn is congruent to ops thenlm is congruent to op,mn is congruent to ps andnl is congruent to so.And similarly with the corresponding angles of the two triangles.Unless the two triangles are equilateral, these relationships will NOT apply if the order of one of the triangles is altered.

In a geometric proof, reasons to support each step can include definitions, postulates, theorems, and previously proven statements. For example, one might use the definition of congruent triangles to justify that two triangles are congruent, or apply the Pythagorean theorem to establish a relationship between the sides of a right triangle. Logical reasoning and established properties of geometric figures also serve as essential support for each step in the proof.
To use the SAS (Side-Angle-Side) postulate to prove two triangles congruent, you need to establish that you have two sides of one triangle that are equal in length to two sides of the other triangle, along with the included angle between those two sides being congruent. Specifically, you need the lengths of the two sides for both triangles and the measure of the angle between those sides in at least one of the triangles. If this information is provided, you can apply the SAS postulate effectively.
