# Python: Calculate the hypotenuse of a right angled triangle

## Python Basic: Exercise-60 with Solution

Write a Python program to calculate the hypotenuse of a right angled triangle.

From Wikipedia,
A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse. If the lengths of all three sides of a right triangle are integers, the triangle is said to be a Pythagorean triangle and its side lengths are collectively known as a Pythagorean triple.

Pictorial Presentation: Sample Solution-1:

Python Code :

``````from math import sqrt
print("Input lengths of shorter triangle sides:")
a = float(input("a: "))
b = float(input("b: "))
c = sqrt(a**2 + b**2)
print("The length of the hypotenuse is:", c )
```
```

Sample Output:

```Input lengths of shorter triangle sides:
a:  3
b:  4
The length of the hypotenuse is: 5.0
```

Sample Solution-2:

Python Code:

``````def test(x, y):
h = (x**2 + y**2)**0.5
return h
print(test(3,4))
print(test(3.5,4.4))
```
```

Sample Output:

```5.0

## Python: Tips of the Day

Builds a list, using an iterator function and an initial seed value:

Example:

```def tips_unfold(fn, seed):
def fn_generator(val):
while True:
val = fn(val)
if val == False: break
yield val
return [i for i in fn_generator([None, seed])]

f = lambda n: False if n > 50 else [-n, n + 10]
print(tips_unfold(f, 10))
```

Output:

```[-10, -20, -30, -40, -50]
```
