What is the difference between a repeating and decimal and a terminating decimal

here you go :)

Step-by-step explanation:

Terminating decimals: these have a finite number of digits after the decimal point.

 Recurring decimals: these have one or more repeating numbers or sequences of numbers after the decimal point, which continue infinitely.

Hello :
A(-2, -5), B(-3, 2), and C (1, -2) 
calculate : AB² , AC² ,BC²
 AB² = ( -3  +2   )² +  ( 2  +5  )² =50
AC² = ( 1  +2  )² +  ( -2  +5   )²  =18
BC² = (  1 +3  )² +  ( -2  - 2  )²  = 32
by petagor rule  :  AB² =  AC² + BC²(ABC is a right triangle in : C )
