It looks like you're referring to a problem involving
congruent triangles and a
geometric proof, but I don't see the actual image or text of the problem. However, based on your description — "I uploaded an image with a task" — and the mention of "Congruent Triangles," I can help guide you through solving such problems
if you provide the details.
But since I can't view images, I’ll explain how to approach
typical congruent triangle problems and what kind of information is usually required.

🔷 Common Congruent Triangle Problem Format:
You’re often asked to prove that two triangles are congruent using one of the following criteria:
-
SSS (Side-Side-Side)
-
SAS (Side-Angle-Side)
-
ASA (Angle-Side-Angle)
-
AAS (Angle-Angle-Side)
-
HL (Hypotenuse-Leg) – for right triangles

🔷 Example Problem (Typical):
> Given:
> - \( \overline{AB} \cong \overline{CD} \)
> - \( \overline{BC} \cong \overline{DA} \)
> - \( \angle ABC \cong \angle CDA \)
> Prove: \( \triangle ABC \cong \triangle CDA \)
---
🔷 Step-by-Step Solution:
1.
Identify the given information:
- Two sides and the included angle are congruent.
- So we use
SAS.
2.
Write the proof:
| Statement | Reason |
|---------|--------|
| 1. \( \overline{AB} \cong \overline{CD} \) | Given |
| 2. \( \overline{BC} \cong \overline{DA} \) | Given |
| 3. \( \angle ABC \cong \angle CDA \) | Given |
| 4. \( \triangle ABC \cong \triangle CDA \) | SAS Congruence Postulate |

🔷 Tips for Solving Congruent Triangle Problems:
1.
Label all known parts (sides, angles, midpoints, perpendiculars).
2.
Look for shared parts (e.g., a common side between two triangles).
3.
Use definitions:
- Midpoint → divides segment into two equal parts
- Perpendicular → forms right angles
- Vertical angles → congruent
4.
Choose the correct congruence criterion based on what’s given.
5.
Be careful about order when naming triangles (e.g., \( \triangle ABC \cong \triangle DEF \) means A ↔ D, B ↔ E, C ↔ F).

✔ If You Can Provide the Problem:
Please type out the
text of the problem or describe the image (e.g., diagram details, what's given, what needs to be proven), and I’ll solve it step by step.
For example:
> "In the figure, AB = CD, AD = BC, and BD is a diagonal. Prove that triangle ABD ≅ triangle CDB."
Then I can give you the full solution!
