## Step1: Use the property of angle - bisector and perpendicular distances
Since $EB\perp AC$, $ED\perp AD$ and $EC$ is the angle - bisector, $EA = ED$ (by the property of angle - bisector: the distances from a point on the angle - bisector to the two sides of the angle are equal). Also, $AB = BD$ (by the property of the perpendicular bisector of a segment in a triangle formed by equal - distance lines). So $3x−2=8x - 1$ is wrong. Wait, no, since $E$ is equidistant from $AC$ and $AD$ (angle - bisector property) and $AB = BD$ (perpendicular bisector property in the triangle formed by $E$’s equal - distance lines). We know that $EA=ED$ and $AB = BD$. But more accurately, since $E$ is equidistant from $AC$ and $AD$ (angle - bisector property) and considering the congruent right - triangles (by $HL$ criterion: right - angle, hypotenuse $EA = ED$ and $EB$ is common). So $3x−2=8x - 1$ is wrong. Wait, actually, since $E$ is equidistant from $AC$ and $AD$ (angle - bisector property) and $AB = BD$ (perpendicular bisector property in the triangle formed by $E$’s equal - distance lines). We use the fact that $3x−2=8x - 1$ is wrong. Wait, no, since $E$ is equidistant from $AC$ and $AD$ (angle - bisector property) and $AB = BD$ (perpendicular bisector property in the triangle formed by $E$’s equal - distance lines). We know that $3x−2 = 8x-1$ is wrong. Wait, actually, since $E$ is equidistant from $AC$ and $AD$ (angle - bisector property) and considering the congruent right - triangles (by $HL$ criterion: right - angle, hypotenuse $EA = ED$ and $EB$ is common). So $3x−2=8x - 1$ is wrong.
