Find a Pythagorean triplet (a, b,c) such that 0<a < b < c, a^2+b^2=c^2, (b+c) = a*a

To find a Pythagorean triplet \((a, b, c)\) such that \(0 < a < b < c\), \(a^2 + b^2 = c^2\), and \((b + c) = a^2\), let's solve this step-by-step.

### Step 1: Write the Pythagorean Triplet Condition
We need:
\[
a^2 + b^2 = c^2
\]
This is the standard Pythagorean theorem for a right triangle.

### Step 2: Apply the Additional Condition
The problem also requires:
\[
b + c = a^2
\]

### Step 3: Check Small Values of \(a\)
To find integer values of \((a, b, c)\) that satisfy both conditions, let’s test a few small values for \(a\) to see if there are any solutions.

1. **Let \(a = 3\):**
   - If \(a = 3\), then \(a^2 = 9\).
   - We need \(b + c = 9\) and \(a^2 + b^2 = c^2\).

   - Trying \(b = 4\) and \(c = 5\):
     - \(3^2 + 4^2 = 5^2\)
     - \(9 + 16 = 25\), which is true.
     - Also, \(b + c = 4 + 5 = 9\), which matches \(a^2\).

So, \((a, b, c) = (3, 4, 5)\) is a valid solution that satisfies both conditions:
1. \(a^2 + b^2 = c^2\)
2. \(b + c = a^2\)

### Final Answer
The Pythagorean triplet that satisfies both conditions is:
\[
(a, b, c) = (3, 4, 5)
\]
