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

Python: Tips of the Day

Iterating over a dictionary:

print("Input three integers(sides of a triangle)")
int_num = list(map(int,input().split()))
x,y,z = sorted(int_num)
if x**2+y**2==z**2:
    print('Yes')
else:
    print('No')

Python: Tips of the Day

You can turn a set into an immutable set

This way, you can no longer modify it:

my_set = frozenset(['a', 'b', 'c', 'd'])

my_set.add("a")

If you do that, an error will be thrown:

AttributeError: 'frozenset' object has no attribute 'add'

In this shot, we will discuss how to generate a right-angled triangle using stars in Python.

We can print a plethora of patterns using python. The basic and only prerequisite for this is a good understanding of how loops work in Python. Here, we will be using simple for loops to generate a right-angled triangle using stars.

Description

A right-angled triangle must have one angle equal to 90 degrees.

To execute this using Python programming, we will use two for loops:

• An outer loop: To handle the number of rows.
• An inner loop: To handle the number of columns.

Code

Let us see the code snippet below to understand it better.

# Number of rows
rows = 5

# Outer loop to handle the rows
for i in range(rows):
    
    # Inner loop to handle the columns
    for j in range(i + 1):
        
        # Printing the pattern
        print("*", end=' ')
    
    # Next Line
    print()

Explanation

• In line 2, we take the input for the number of rows (i.e. the length of the triangle).

• In line 5, we create a for loop to handle the number of rows.

• In line 8, we create a nested for loop (inner loop), to handle the number of columns.

• In line 11, we print the pattern (*). Any other character could be printed by being in the print statement. The end statement helps us to be on the same line till the loop finishes.

• In line 14, we use print(), to move to the next line.

We can print a plethora of patterns using Python. The basic and only prerequisite is a good understanding of how loops work in Python. Here, we will be using simple for loops to generate a right-angled triangle using stars and numbers.

Description

A triangle is said to be right-angled if and only if it has one angle equal to 90 degrees.

To execute this using Python programming, we will be using two for loops:

• An outer loop to handle the number of rows.
• An inner loop to handle the number of columns.

Code

Let’s look at the code snippet below to understand it better.

# Number of rows
rows = 5

# Outer loop to handle the rows
for i in range(rows):
    
    # Inner loop to handle the columns
    for j in range(i + 1):
        
        # Printing the pattern
        print(j+1, end=' ')
    
    # Next Line
    print()

Explanation

• In line 2, the input for the number of rows (i.e., length of the triangle) is taken.

• In line 5, we create a for loop to handle the number of rows.

• In line 8, we create a nested for loop (inner loop), to handle the number of columns.

• In line 11, we print the pattern, and we have printed j+1, which results in iteration from 1 (since j + 1) to length of i in each row. i keeps increasing with increasing rows, and so the numbers keep increasing as the line number increases.

• In line 14, we use print() to move to the next line.

How do you write a right

To print the right-angled triangle in Python, we can take the input from the user for the length of the triangle. As you can see, Input is taken from the user as (x). As we know that a for loop is used for iterating over a sequence. Then using nested for loop, you can print the right-angled triangle.

How do you print numbers on a right

Example -.

# This is the example of print simple reversed right angle pyramid pattern..

rows = int(input("Enter the number of rows:")).

k = 2 * rows - 2 # It is used for number of spaces..

for i in range(0, rows):.

for j in range(0, k):.

print(end=" ").

k = k - 2 # decrement k value after each iteration..

for j in range(0, i + 1):.

How do you find the area of a right

Python.

b = 5..

h = 8..

area = ( b * h) / 2..

print("Area of Right Angle Triangle is :");.

print(area);.

How do you program a triangle in Python?

Programs to print triangles using *, numbers and characters In the first loop, we iterate from i = 0 to i = rows . The second loop runs from j = 0 to i + 1. In each iteration of this loop, we print i + 1 number of * without a new line. Here, the row number gives the number of * required to be printed on that row.
