In the plane rectangular coordinate system, the coordinates of point a are (3,4), and B is a point on the X axis. If the triangle ABC is an isosceles triangle, then the coordinates of point B are (3,4) Marked as

In the plane rectangular coordinate system, the coordinates of point a are (3,4), and B is a point on the X axis. If the triangle ABC is an isosceles triangle, then the coordinates of point B are (3,4) Marked as

Let B coordinate (B, 0) a coordinate be (3,4) | OA | = √ (3 & # 178; + 4 & # 178;) = 5 △ ABO be isosceles triangle. There are three cases: (1) OA = ob, | B | = 5, B = - 5, or 5B1 (- 5,0), B2 (5,0) (2) Ao = Bo, B = 2xa = 2 * 3 = 6b3 (6,0) (3) Bo =
