👉 In geometry, a midline is a line that divides an object into two congruent halves. It's also known as a perpendicular bisector or a bisector of a segment. Midlines are often used in mathematics to find angles and lengths in geometric figures. For example, in the figure below: ``` 8 / \ 6 4 / 5 ``` The midline at point P divides the triangle into two triangles with equal areas, because it
