Graphing Ordered Pairs I can solve problems by graphing ordered pairs using absolute value to calculate distances. Coordinate Plane A grid Used to locate points Quadrant II -, + -, Quadrant III Quadrant I +, + +, Quadrant IV Ordered Pair Indicates a point on a coordinate plane (4, 2) (X, Y) X comes before y just like it does in the alphabet. Graphing an Ordered Pair Start at the lobby (0,0) (The point of Origin) 1. Walk to the elevator go either to: a) the right (positive +) b) or to the left (negative -) 2. Take the elevator: a) up (positive +) b) or down (negative -) Activity 1 Activity 2 Checking out the Zeros Team Time Two Dimensional Object • A shape that only has two dimensions (such as width and height) and no thickness. • Its flat (doesn’t pop out at you) • Also Known as: 2D object Square A 4-sided flat shape with straight sides where: • All sides have equal length • And every interior (inside) angle is a right angle (90 °) Rectangle • A 4-sided flat shape with straight sides where all interior angles are right angles (90°). • Also opposite sides are parallel and of equal length. Equilateral Triangle • A triangle with all three sides of equal length. • All the angles are 60° Right-Angled Triangle • A triangle that has a right angle (90°) Parallelogram • A 4-sided flat shape with straight sides where opposite sides are parallel. Also: • opposite sides are equal in length • and opposite angles are equal (angles "a" are the same, and angles "b" are the same) Vertex (Vertices) • A point where two or more straight lines meet. A corner. • The plural of vertex is "vertices". There are 5 vertices on this pentagon. How many Vertices? What is it called? How many Vertices? What is it called? How many Vertices?
