Congruent
If you mean which triangle has at least two lines of symmetry, I can answer your question: an equilateral triangle has three lines of symmetry-- one passing through the center of each side and through the opposite point, perpendicular to the side.
If all three lines are parallel, there are zero points of intersection. If all three lines go through a point, there is one point of intersection. If two lines are parallel and the third one crosses them, there are two. If the three lines make a triangle, there are three points.

A point has an infinite amount of lines passing through it.
Perpendicular lines passing through a point are at right angles to each other.

any of a set of straight lines passing through one point.
A regular polygon triangle is an equilateral triangle. It has three lines of symmetry: a line passing through each vertex and the mid-point of the opposite side. These are the three medians or altitudes or perpendicular bisectors or angle bisectors of the triangle - they are all the same lines.
If all three lines are parallel, there are zero points of intersection. If all three lines go through a point, there is one point of intersection. If two lines are parallel and the third one crosses them, there are two. If the three lines make a triangle, there are three points.
Magnetic north (which is a little different from north. as defined as the meeting point of all lines drawn perpendicular to the equator and passing through the northern hemisphere)
An infinite number of lines can pass through a point.
You need two points to determine a line. A single point can have an infinite number of lines passing through it.
There are three lines.
All the lines meet at one point: a single solution. All the lines are the same: infinitely many solutions. At least one of the lines does not pass through the point of intersection of the others: no solution.
these lines are called intersecting lines
