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

1. perpendicular

2. parallel

3. perpendicular

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
