25.) Slope of AB = 5

Slope of CD = -1/5

Perpendicular

26.) Slope of EF = -3/5

Slope of GH = -3/5

Parallel

Step-by-step explanation:

Use this formula to find slope.

Parallel lines have the same slope

Perpendicular lines have the opposite reciprocal and sign

25.)

Plug in AB slope is 5

2 - 7/ 3 - 4 = -5/-1 = 5

Plug in for CD slope is -1/5

3 - 4/ 2 - -3 = -1/5 = -1/5

The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.

26.)

Plug in EF slope is -3/5

1 - 4/ 3 - -2 = -3/5 = -3/5

Plug in GH slope is -3/5

-5 - -2/ 4 - -1 =  -3/5 = -3/5

The lines EF and GH are parallel lines because they have the same slopes.

Hope this helps ya!
