Guided Notes: Congruency - Midpoint - Distance

Congruent Segments: _Line segments that have the same length________

Ex 1. Determine if the following segments are congruent.

Ex 2. Suppose point AB and BC are congruent segments. Determine the value of x.

Guided Notes 1.2/1.3 Name:______________________________ Midpoint and Distance Formulas

Midpoint:_the point that divides the segment into two

congruent segments.

Segment bisector:_a point, line, ray, or plane that

intersects the segment at its midpoint.

Ex 1. Suppose M is the midpoint of segment PN. What is the length PM?

2.) ON YOUR OWN… Suppose K is the midpoint of JL, determine the length of JL.

The Midpoint Formula:

If A(x1, y1) and B(x1, y1) are points in a coordinate plane, then the midpoint M

of has coordinates

.

Ex 1. Use the midpoint formula to find the midpoint of segment with

C(1, -3) and D(4, 2).
