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.
Parallel lines of light rays hitting a convex lens will converge towards a single point after passing through the lens. This point is known as the focal point, where the light rays meet and diverge after passing through the lens.
Only one line can be drawn parallel to plane P that passes through point A. This line will be oriented in the same direction as the plane, remaining equidistant from it. All other lines passing through point A will either intersect the plane or be skew to it.
An infinite number of lines can pass through a point.
The equation of a vertical line passing through the point (a, b) is x a.
Through two given lines, there can be either zero, one, or infinitely many lines that can be drawn, depending on their relationship. If the two lines are parallel, no line can pass through both. If they intersect, exactly one line can be drawn through their intersection point. If they are coincident (the same line), then infinitely many lines can be drawn through them.
The frequency of the waves passing through the reference point increases when more waves pass through in a period of time. Frequency is the number of waves passing through a point in one second and is directly proportional to the number of waves passing through that point in a given time period.
