Segment Addition Postulate Calculator

The Segment Addition Postulate Calculator on Omni Calculator applies the geometric principle that if a point lies between two endpoints on a line, the sum of the two smaller segments equals the total length. Users input the lengths of two adjacent segments (AB and BC) to find the total length (AC), or they can use the tool to verify whether a specified point is collinear by checking if the combined segment lengths match the total. The result provides the calculated total length and a confirmation of collinearity based on the entered values. The Omni Calculator version distinguishes itself by offering dual functionality: it not only computes the total segment length but also includes a dedicated mode to check if points are collinear. The interface presents clear labeled input fields for AB, BC, and AC, alongside a toggle to switch between 'find the total length' and 'check if points are collinear' modes. The page further enriches the user experience with a worked example, a definition of the postulate, and a brief explanation of how the calculator verifies collinearity, all presented within a straightforward design that avoids unnecessary complexity.
