Lisa is writing a coordinate proof to show that the diagonals of a square are perpendicular to each other. she starts by assigni
ng coordinates as given. a square is graphed on a coordinate plane. the horizontal x-axis and y-axis is solid and grid is hidden. the vertices are labeled as k, g, h and j. the vertex labeled as k lies on begin ordered pair 0 comma 0 end ordered pair. the vertex labeled as g lies on begin ordered pair 0 comma a end ordered pair. the vertex labeled as j lies on begin ordered pair a comma 0 end ordered pair. one vertex is unlabeled. diagonal k h and g j are drawn. drag and drop the correct answers to complete the proof. since ghjk is a square, the coordinates of h are (a, ). the slope of kh¯¯¯¯¯¯ is . the slope of is −1 . the product of the slopes of the diagonals is . therefore, kh¯¯¯¯¯¯ is perpendicular to gj¯¯¯¯¯ . 10−1agj¯¯¯¯¯gk¯¯¯¯¯¯
Your a cheater, k12 will expel cheaters..... jk lol but the answers are
Since GHJK is a square, the coordinates of H are (a, a). The slope of KH¯¯¯¯¯¯ is 1. The slope of GJ¯¯¯¯¯ is −1 . The product of the slopes of the diagonals is −1. The product of the slopes of the diagonals is −1.
Good luck, and really study, because the finals test will be difficult, and use the geometry reference guide.... It covers the fundamentals
With a square, all you need to do to find the length of one side is to divide the perimeter by 4. If it is the area you are calculating, then you need to find the square root. For that equation the answer is 24.
