How do you find the shortest distance between two parallel lines?
The shortest distance between 2 parallel lines is a perpendicular drawn between 2 parallel lines the diagram shows it clearly 1 parallel line ------------------------------------|-------------------------------------------------------------------- | | | the vertical line is the shortest distance | | ------------------------------------|------------------------------------------------------------------- 2nd parallel line
Are the medians of a triangle equidistant from each vertex?
Every triangle has three medians, just like it has three altitudes, angle bisectors, and perpendicular bisectors. The medians of a triangle are the segments drawn from the vertices to the midpoints of the opposite sides. The point of intersection of all three medians is called the centroid of the triangle. The centroid of a triangle is twice as far from a given vertex than it is from the midpoint to which the median from that vertex goes. For example, if a median is drawn from vertex A to midpoint M through centroid C, the length of AC is twice the length of CM. The centroid is 2/3 of the way from a given vertex to the opposite midpoint. The centroid is always on the interior of the triangle.
How do you identify which lines are parallel?
Well the easiest way to do this (but in no way perfectly accurate) would be to extend both lines as far as you can on either end. If the lines never meet on either side you've got parallel lines. Well, either that or you're not drawing straight lines, or you haven't drawn them out far enough. The accurate way would be to draw a perpendicular line from one of them towards the other and measure the angle against the second line. If it's perpendicular to both lines you've got yourself parallel lines.
