# How to determine if two triangles are congruent with coordinates

• Jan 09, 2006 · To convert from world coordinates to triangle vertices, first find the lower left corner of the rhombus (u, v) using algebra, or by inverting the i.x,j.x,i.y,j.y matrix. The rhombus contains two triangle faces. To determine which face the point is in, look at the edge that divides the two triangles inside each rhombus (edge “E” in Figure 10).

• Jan 04, 2019 · has two congruent sides, so it is isosceles. Here, NJ = JL . Point N is at origin, so its coordinates are (0, 0). Point L is on the x-axis, so its y-coordinate is 0. The coordinates of L are (3 a, 0). Find the coordinates of point J , that makes the triangle isosceles. This point is half way between N and L, so the x-coordinate is 1.5 a.

• Find the missing coordinates of the triangle. We know right off the bat that our first coordinate is the origin. That would be (0, 0). Halfway there. We know its y coordinate has to be 0 because it's on the x-axis. Since its vertical side goes straight down from (a, b), the remaining point is the horizontal distance away from the origin.
