Jkl has vertices at j(-4,-2) k(1,-1) and l (-2,-4). determine if jkl is a right triangle.

Yes, it is a right triangle

Step-by-step explanation:

Hello, I think I can help you with this

you can solve this finding the lengths and then find the longest length, it would be the hypotenuse, and the lengths must fit to

Step 1

you can find the distance between 2 points P1 and P2 using:

Let

P1=J(-4,-2)

P2=K(1,-1)

P3=L(-2,-4)

distance JK=P1P2=

distance KL=P2P3=

distance JL=P1P3=

so the lengths are

The longest length is JK, hence this is the hypotenuse

Step 2

Check

hence this is a right triangle.

Have a nice day
