Oct 1, 2010 · If you need the intersection point, then the answer by OMG_peanuts is a faster approach. However, if you just want to find whether the lines intersect or not, you can do so by using the line equation (ax + by + c = 0). The approach is as follows: Let's start with two line segments: segment 1 and segment 2.
There are two cases to consider when determining if two line segments $AB$ and $CD$ intersect: (1) The line segments are not co-linear (top three images in the following figure); (2) the line segments are co-linear (bottom two images).
Here you will learn about intersecting lines, including how to find the point of intersection of two straight lines and how to solve simultaneous equations graphically and algebraically.
I need to find the intersection point of 2 line segments (lines are finite, i.e., they have end points). e.g. segment 1 from $(x_1, y_1)$ to $(x_2, y_2)$ -- segment 2 from $(x_3, y_3)$ to $(x_4, y_4)$ you can assume $m_1$ and $m_2$ are the gradients of segment 1 and segment 2 respectively
Drag any of the points A,B,C,D around and note the location of the intersection of the lines. Drag a point to get two parallel lines and note that they have no intersection. Click 'hide details' and 'show coordinates'. Move the points to any new location where the intersection is still visible. Calculate the slopes of the lines and the point of ...
Here we will learn about intersecting lines, including how to find the point of intersection of two straight lines and how to solve simultaneous equations graphically and algebraically. There are also intersecting lines worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
Following are detailed steps. 1) Let there be n n given lines. There must be 2n 2n end points to represent the n n lines. Sort all points according to x coordinates. While sorting maintain a flag to indicate whether this point is left point of its line or right point. 2) Start from the leftmost point. Do following for every point.
