Question

how to write code for hollow rigth angled triangle with different shapes of three side of a triangle

Answer 1

A triangle is said to be right-angled if it has an angle equal to 90 degrees on its left side.

We will use 2 for loops:

• Outer loop: To handle the number of rows.
• Inner loop: To handle the number of columns.

  # Number of rows
n = 5
# Loop through rows
for i in range(1, n+1):
    # Loop through columns
    for j in range(1, n+1):
        # Printing Pattern
        if (i == j) or (j == 1) or (i == n):
            print("*", end=" ")
        else:
            print(" ", end=" ")
    print()  

Output:

*         
* *       
*   *     
*     *   
* * * * *
