How do you find the midpoint of a line segment?

Back

The midpoint of a line segment connecting two points (x1, y1) and (x2, y2) is found using the formula: Midpoint = ( (x1 + x2)/2 , (y1 + y2)/2 ).

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape. This can be proven using criteria such as SSS (Side-Side-Side), SAS (Side-Angle-Side), AAS (Angle-Angle-Side), and ASA (Angle-Side-Angle).
