Please help on this problem :(

1: a

2: a

3: a

4: b

Step-by-step explanation:

a right triangle means the pythagorean theorem applies

a^2 + b^2 = c^2

is true for the triange

a and b are the two shorter sides and c is the long side

test with values to see if true

6^2 + 8^2 = 10^2

36 + 64 = 100

100 = 100

true, it is a right triangle

3 root^2 + 8 root^2 = 11 root^2

3 + 8 = 11

11=11

true, it is a right triangle

3^2+ 10 root^2 = 19 root^2

9 + 10 = 19

19=19

true, it is a right triangle

3^2 + 5^2 = 6^2

9+25= 36

34= 36

false not a right triangle

i hope this helps
