finding missing angles
Parallel lines are lines at exactly the same angle
Two, or more, lines which are at exactly the same angle (like the
tire tracks from the car must be) are called parallel lines. We use
Even if you
little v-shaped tick marks to indicate sets of parallel lines or line
segments on a sketch.
Parallel lines can never meet or cross each other, even if you
stretch them for miles and miles and miles.…
lines never cross
closer or farther away.
The distance between the lines
is constant—they never get
If you have more than one set of parallel lines on the same
sketch then you need to use a different number of tick marks
on each set to be able to tell them apart.
Two different sets
of parallel lines.
If parallel lines are always at the
same angle, and our tire tracks
are parallel, what should this
angle here be?
