<em>Two </em>or <u>more</u> triangles are said to be congruent if and only if they have <u>equal</u> lengths of <em>sides</em> and <u>equal</u> measures of <em>angles</em>.

Thus, the required <u>proof</u> is as shown below:

   <u>STATEMENTS </u>                                             <u>REASONS</u>

1. ΔABC and ΔDEC with AB ≅ DE;

  BC ≅ EC; <1 ≅ <2                                          Given

2. <1 and < ABC; < 2 and <DEC are sup     <u>Sum</u> of angles on a <em>straight </em>line

3. <ABC ≅ <DEC                                <em>Congruent</em> angles of <u>similar</u> triangles

4. ∴ΔABC ≅ ΔDEC                              <em>Side-Angle-Side</em> (SAS) postulate

5. ∴<ACB ≅ <DCE                                         CPCTC postulate

In triangles ABC and LMN, ∠A ≅ ∠L, ∠B ≅ ∠M, and ∠C ≅ ∠N. Is this information sufficient to prove triangles ABC and LMN congruent
ipn [44]

Answer:

No

Step-by-step explanation:

No. We have 3 angles of triangle ABC congruent to 3 corresponding angles of triangle LMN. That is AAA. To use ASA, you need two angles and an included side. With three angles, you can prove the triangles similar, but not congruent.
