Measure segments on the coordinate plane. Use algebra to calculate lengths of segments.
Postulate: A rule accepted without proof.
Congruent: Equal measure
Expression: Combination of variables, numbers and arithmetic operations. There is no equal sign.

The 2014 Winter Olympic Games were held in Sochi, Russia. The distance between Washington, D.C. and Rome is about 4480 miles. The distance between Washington, DC and Sochi is about 5500 miles. What is the distance between Rome and Sochi?
Hint: Write an expression only, this is NOT an equation. You DO NOT have to solve for x!
Hint: Write an expression only, this is NOT an equation. You DO NOT have to solve for y!
Point R is between Q and S on line segment QS. Write an equation, then solve for x.
Hint: Sketch a picture and label what you know.
QR=13+2x
RS=12
QS=x+32
Find BD.
Graph the following points. Are AB and CD congruent?
A(1,3), B(1,-3), C(3,-2), D(-3,-2)
For line segment AC, Point B is in between points A and C. Write an equation in terms of x, then solve for x.
AB = 2x+10
BC = x-4
AC = 21
