 Two or more lines that never touch and stay the same distance apart.

 Perpendicular lines consist of at least two intersecting to form 90° angles.

 The midpoint is a point on a line or in a set of points that is the center.  On a line the midpoint is the middle  If given two points you can use the midpoint formula to find the midpoint.

 Ex  To find Distance the formula above can be used.  The Distance Formula is used to find the distance between two given points  Distance can help find if two triangles or figures are congruent

 Find the distance of point A and B.

 First know what points you are using.

 Find the distance of point A and B.  First know what points you are using.  Second Plug into formula.

 Find the distance of point A and B.  First know what points you are using.  Second Plug into formula.  Then Solve for anwser.

 Is point c a midpoint?  Are line ACB and Line L parallel?  Are line L and line K Perpendicular? A CB

 Is point c a midpoint? ◦ - Yes ◦ This symbol means the parts of the line are congruent and have C in common.  Are line ACB and Line L parallel?  Are line L and line K Perpendicular? A CB

 Is point c a midpoint? ◦ - Yes  Are line ACB and Line L parallel? ◦ -Yes ◦ - This symbol shows that they are parallel.  Are line L and line K Perpendicular? A CB

 Is point c a midpoint? ◦ - Yes  Are line ACB and Line L parallel? ◦ -Yes  Are line L and line K Perpendicular? ◦ - No ◦ - They are not at a 90° angle. A CB

 What is the distance between these two lines?

 First find the slope of both lines.

 What is the distance between these two lines?  First find the slope of both lines.  Next find a point in common using a Perpendicular slope.

 What is the distance between these two lines?  First find the slope of both lines.  Next find a point in common using a Perpendicular slope.  Last plug in to distance formula.

 Find the distance.
