Plotting Points (x,y): Dynamic Illustration

[b][color=#000000]A COORDINATE is a NUMBER or a LETTER that indicates LOCATION. [/color][/b][color=#000000][br]Did you ever play Milton Bradley's game [/color][b][color=#000000]Battleship[/color][/b][color=#000000] as a kid? [br]If so, you dealt with coordinates! "A5" was either a "hit" or a "miss", right? [br]In this game, the "A" and the "5" are called coordinates. [br][br]Your mobile device can indicate your latitude and longitude. [br][b]LATITUDE and LONGITUDE[/b] are numbers that help tell a person his/her [b]LOCATION.[/b] [br]Thus, [b]LATITUDE and LONGITUDE[/b] are said to form a pair of [b]COORDINATES. [/b] [br] [br][/color]Note the coordinate plane below. [color=#0000ff]Press the [/color][color=#38761d]"New Example"[/color][color=#0000ff] button. After doing so press [/color][color=#bf9000]"Plot Point"[/color][color=#0000ff]. [br][/color]Be sure to watch the specific dynamics of how to plot a point correctly. Repeat the [b][color=#0000ff]colored step[/color][/b] above approximately 10 times. [color=#000000]Then, go to the link indicated below the applet. [/color]
[color=#000000]Once you're confident in your ability to plot a point given its coordintes, [url=https://www.geogebra.org/m/AbRPAY8V]click here[/url] to put into practice what you've just learned! [/color]

Distance in the Coordinate Plane (With Hints)

Discovery Lesson (Can be used without interactive figure below)

Midpoint and Endpoint Coordinates Action!

Here, point A is an endpoint and point M is a midpoint. Move A and M where you'd like and slide the slider to find the other endpoint (B).

Graph to Slope Task

[color=#000000]Discovery Lesson Activity: [br][/color][color=#0000ff][b]Move the end points and observe how slope changes. [br][/b][/color]
How is the rise best described?
How is the run best described?
Under what conditions is the slope an integer?
When is the slope a unit fraction ( a unit fraction has a numerator of 1)

Slope to Angle Measure Calculator (I)

[b]Students: [color=#1551b5]This applet is to be used when trying to use coordinate geometry prove two triangles (drawn in the coordinate plane) congruent.[/color] [/b][br][br][color=#c51414][i]You already know how to calculate the distance between any two points in the coordinate plane, so finding the length of any side of a triangle should be an easy task. [br]However, calculating the measure of an interior angle between two sides of a triangle is a bit more complicated.[/i][/color][br][br][color=#1551b5][b]If you need to calculate the angle measure between any two sides of a triangle, follow the directions in the applet below: [/b] [/color]
