Is a triangle with side lengths 8 cm, 9 cm, and 10 cm a RIGHT triangle? Explain why or why not.

the answer is no

Step-by-step explanation:

for a triangle to be right angle the square of the longest side must be equal to the sum of the other two sides

meaning;

10^2=8^2+9^2

100= 64+ 81

100= 145

this above expression is wrong

of course 100 is not equal to 145.

I hope I explained well. pls if I did mark me the brainliest

113.42

i hope that is right.

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
