If point A has coordinates 3 5 point B has coordinates 3 2 and ABCD is a square which of the following could be the coordinates of point C A 4 2 B 6 2 C 6 6 D 4 6 E 8 2 2. If 1 is a horizontal line passing through 1 8 and 2 is a vertical line passing through -3 4 then at what point do 1 and 2 intersect A -3 8 B 1 4 C -1 6 D -2 12 E 0 0 6. What is the area in square units of the shaded region in the figure above 3. The point -3 4 is on a circle with its center at the origin. Which of the following points must also be on the circle I. 0 -5 II. -4 -3 III. 3 4 A 32 B 33 C 34 D 35 E 36 A I only C I and II only E I II and III B II only D II and III only 4. If the point 3 -7 is the center of a circle and the point 8 5 is on the circle what is the circumference of the circle Note Figure not drawn to scale. 7. Points A and B lie on the line y 6 as shown above. Lines 1 and 2 pass through the origin and 1 has a slope of 12. If the distance from A to B is 4 what is the slope of line 2 A 13n D 25n B 15n E 26n C 18n 5. In the figure above point E is to be drawn so that ACDE has the same area as AABC. Which of the following could be the coordinates of E A 16 5 B 3 8 C 5 12 D 2 16 E 4 24 CHAPTER 10 ESSENTIAL GEOMETRY SKILLS 381 Answer Key 4 Coordinate Geometry Concept Review 4 1. -2 1 2. 2 3. 4. Your line should be vertical straight up and down and pass through B. 5. The x-coordinate of all the points is 3 so 1 can be described by the equation x 3. 6. 2 should be horizontal straight across and pass through B. 7. 3 should be a horizontal straight across line one unit below the x-axis. 8. -2 5 9. 1 8 Notice that the new segment must be the same length as AB but its slope is the negative reciprocal of AB s slope that is -5 2. 10. 8 5 11. The area of the rectangle is 108 and its length DC is 14 - 2 12. So its height is 108 12 9. Therefore k - 1 9 and k 10. m 14 n 10 p 1 SAT Practice 4 1. B The vertices of a square must .
