And here in this question, you also use similar triangles to find the coordinates of points, q, right? and another point, let's say p, uh, point q that basically intersects, uh, two points p1 and p2, right? so let me join it in the beta.
00:24
It's not really informative.
00:26
Suppose you have two points p1, right, it has coordinates x1, y1, and d1, and another point, let's say p2, right, so it says here, p2, it does coordinates x2, y, 2, z2, right? now joining these two points, and on the line joining this to points, there's another point, this is a q, right? and this q basically divide this line into two parts, one with lens p, the other with the lines q, right? and the ratio of this p over q is supposed to be r, right? and you ask you find the coordinates for the q, right? well, for example, to use the similar triangles, right? so what we could do is, for example, let's look at x part, let's look at x coordinates.
01:19
Because the y coordinates, z coordinates, basically they can be worked out in a similar way.
01:26
So i just look at x coordinates.
01:28
And for that purpose, what we need to, for example, let's suppose, let's suppose this is the x -axis, right? now let me make the beta...
