Prior to both lessons, we review properties of triangles and quadrilaterals in terms of side length and parallelism and perpendicularity. In a coordinate geometry proof, you begin by placing x and y axes on your diagram. In this chapter, we will look at the basic ideas of: • the distance between two points on the number plane • the midpoint of an interval • gradient (or slope) Line Q has a y-intercept of +9, so if Line S also has a y-intercept of  +9, they would intersect on the y-axis, not in the second quadrant. If we start at the x-intercept of point Q, the point (–15, 0), we would follow the slope of –5/3 over 15 and down 25 to (0, –25). Coordinate Geometry Proofs - Displaying top 8 worksheets found for this concept.. 6) Well, for starters, zero is a multiple of every number, and a line with slope zero, the horizontal line y = –4 passes below (4, –1) and above (5, –6).

Therefore, +1/7 through +5/7 will all slope up, obviously above (5, –6), and all will pass below (4, –1). The slopes of the horizontal sides could simply be stated as being equal to zero, since all horizontal segments have a slope of zero (no rise). The method usually involves assigning variables to the coordinates of one or more points, and then using these variables in the midpoint or … The coordinate geometry proofs require a thorough understanding of the properties of several geometric shapes, such as triangles, rhombus, quadrilaterals, and other polygons.

HSG-GPE.B.4. The following practice questions ask you to apply the midpoint and slope formulas to prove different facts about two different quadrilaterals. Use a ruler to draw straight lines or segments. For those who want to know the “rule”: when a point is reflected over the line y = –x, the coordinates are reversed, and each one takes on its opposite sign. This blending of algebra and geometry is referred to as analytic geometry.
