NEED HELP ASAP 30 POINTS WILL BE GIVEN TO BRAINLIEST
WINSTONCH [101]

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

G(-1,3)\ H(1,2)\ J(-3,-1)

Step 1

<u>Find the slope GH</u>

G(-1,3)\ H(1,2)

substitute in the formula

m=\frac{2-3}{1+1}

m=\frac{-1}{2}

mGH=-\frac{1}{2}

Step 2

<u>Find the slope HJ</u>

H(1,2)\ J(-3,-1)

substitute in the formula

m=\frac{-1-2}{-3-1}

m=\frac{-3}{-4}

mHJ=\frac{3}{4}

Step 3

<u>Find the slope JG</u>

J(-3,-1)\ G(-1,3)

substitute in the formula

m=\frac{3+1}{-1+3}

m=\frac{4}{2}

mJG=2

Step 4

Verify if triangle GHJ is a right triangle

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

so

m1*m2=-1

compare slope GH with slope JG

we have

mGH=-\frac{1}{2}

mJG=2

-\frac{1}{2}*2=-1 -----> side GH and side JG are perpendicular

The triangle GHJ is a right triangle
