Slope of line a: 2/7 slope of line b: 7/2 lines are parallel, perpendicular or neither ?

Lines are neither parallel nor perpendicular

Step-by-step explanation:

Two line are parallel when they have same slope.

Two lines are perpendicular when the product of slope of the two lines are (-).

ie. m₁ * m₂ = -1

They are neither parallel nor perpendicular.

Note: For slopes to be parallel, they must be equal i.e if M1 denote the slope of the first line and M2 the slope of the second line , if they are parallel then M1 = M2 and if they are perpendicular M1 = -1/ M2

step-by-step explanation:

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
