Short Description of Lesson: This is a lesson that introduces or reinforces how to find the distance between 2 points on a coordinate plane by using the absolute value between 2 points or using the distance formula.

Lesson Objectives: Students will learn how to find the distance between two points on a coordinate plane and apply their leaning to find the distance between 2 perpendicular lines on a coordinate plane (Glencoe-Geometry 3.6 Perpendiculars and Distance), transformations in the coordinate plane (Glencoe-Geometry 4.3 Congruent Triangles), SSS on the coordinate plane (Glencoe-Geometry 4.4 Proving Congruence –SSS, SAS) and The Distance Formula (Glencoe-Algebra 1 11.5 The Distance Formula).

Materials / Equipments: Computers, LCD projectors for demonstration, virtual manipulative from http://www.explorelearning.com/index.cfm?method=cResource.dspView&ResourceID=64 , http://www.explorelearning.com/index.cfm?method=cResource.dspView&ResourceID=183 .

Distance Formula Activities I: Students will measure the distance between 2 points using the ruler with a vertical Line. Have student change only the values for y1 and y2 and then they should be able to tell that the distance between any vertical lines is the difference between the absolute value of y1 and y2 or vice versus.

Distance Formula Activities II: Students will measure the distance between 2 points using the ruler with a horizontal line. Have student change only the values of x1 and x2 and then they should be able to tell that the distance between any horizontal lines is the difference between the absolute value of x1 and x2 or vice versus.

Distance Formula Activities III: Students will find the distance between 2 points using the distance formula and the Pythagorean Theorem will also be reviewed. Students should be able to find the distance between 2 points on a coordinate plane after these activities....

...DISTANCE CALCULATION
Because of the near-spherical shape of the Earth (technically an oblate spheroid) , calculating an accurate distancebetweentwopoints requires the use of spherical geometry and trigonometric math functions. However, you can calculate an approximate distance using much simpler math functions. For many applications the approximate distance calculation provides sufficient...

The DistanceBetween Us Essay
In the memoir, “The DistanceBetween Us,” by Reyna Grande, Reyna explains how her and her three siblings managed to grow up without any parents. Mago, Carlos, Reyna and their new sister, Betty, all live a rough life without any real type of love from their parents so they have to rely on each other for guidance and support. The four Grande children formed a special bond over the years that they will...

The distancebetween psychological and social
Emily was often set apart from the town's people because they viewed her as a social icon. She was well respected in the town, because of her father’s wealth and the neighborhood she lives in. This was obvious in the text when it was stated, “Miss Emily had been a tradition, a duty and a care a sort of hereditary obligation upon the town.”...

...The Two-Point Threshold
I. Introduction
In the two-point threshold experiment it is obtained how close two distinct sharp point can be together for a person to feel twopoints instead of one. The value of the two-point threshold is the minimal distance at which the subject can feel two distinct points. The...

The DistanceBetween Us: A Memoir by Reyna Grande
The term “The American Dream” is very broad with many meanings and certainly broader than any single statistic can measure; however we all our own definition of that. Some would say it is building their dream house, going to college, being wealthy, or just having a family. While Reyna Grande’s memoir, The DistanceBetween...

...this is that David Cameroon assassinates anyone who even thinks about with a toothpick, I found out the hard way... Aeroplanes, from a distance, look like beautiful, massive and inviting, winged creatures, inside? They are far from it. Aeroplane architects spend so much time on the outer decor of the plane; they hardly remember there’s an inside as well! If the plane is colourful and has big ‘jets’ then I guess nothing else matters, Right? Right?...

...Torn BetweenTwo Loves
In Mary Shelley's novel Frankenstein, Victor Frankenstein's relationship with Elizabeth Lavenza was for her to be his wife. The means of which Elizabeth was brought into the family was to marry Victor, and Victor felt that way from the first time he ever met Elizabeth. Eventually Victor's mother's dying wish was for him to marry Elizabeth, his adopted sister. Victor would kill his wife because of his obsession with his work and...

...modern manner. Both paintings are portraits; yet, one can find a lot of distinction between the two of them. While the young woman shows a negative connotation, Boccioni’s self portrait shows a lively man with vivid colors that gets the viewer’s attention immediately. Both artists found a way of establishing a human body in different styles using different methods with the brushes. Another difference in the way these two artists painted is that with...
