Math Problem Statement
Solution
The image contains a problem focused on demonstrating that a set of given points are concyclic, meaning they all lie on a common circle.
Here's a breakdown of the approach:
-
General Circle Equation: The equation of a circle is generally given by: Where , , and are constants to be determined.
-
Given Points: The points provided are , , , and .
-
Substitution into the Circle Equation: To prove the points lie on the same circle, we substitute each point into the circle equation. By substituting the coordinates, a system of linear equations in terms of , , and is formed.
-
First Substitution (Point ): Substitute into the general equation: Simplifying this gives:
-
Second Substitution (Point ): Substitute into the general equation: Simplifying this gives:
-
Third Substitution (Point ): Substitute into the general equation: Simplifying this gives:
Next Steps:
You would typically solve this system of linear equations (Equations 1, 2, and 3) for , , and . After solving these, if the constants satisfy the equation when the fourth point is substituted, all points are concyclic.
