All homework is due on this day, regardless of whether or not you have class.
Friday
Used to find the distance when the points are on a graph.
The Distance Formula
If a = b, then a + c = b + c
Addition Property of Equality

you can make up any test, up until when?
One week before the end of the quarter
Used to find the middle point of a line on a graph
The Midpoint Formula
If a = b, then ac = bc
Multiplication Property of Equality
Constructs an angle
Compass
a straight path that has no thickness and extends forever
line
Success is more about good attitude, good habits, and perseverance than natural ability.
"It Takes Zero Talent"
Let A, B, C be collinear points. If B is between A and C, then AB + BC = AC
Postulate 1: Segment Addition Postulate
If a = b, then b can be substituted for a in any expression.
Substitution Property of Equality
Projects an image
MIRA
it names a location and has no size
point
Related to the Pythagorean Theorem
The Distance formula
If a = b, then a - c = b - c.
Subtraction Property of Equality
Tools needed to bisect an angle
straight-edge (or ruler) and a compass
a statement that has been proven
There are many ways to demonstrate your understanding of a concept besides traditional ways.
"Show What You Know"
Finding the average of two x-coordinates and the average of two y-coordinates
The Midpoint Formula
If a = b and c ≠ 0, then a/c = b/c.
