Question

Lisa is writing a coordinate proof to show that the diagonals of a square are perpendicular to each other. she starts by assigning 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¯¯¯¯¯¯

Answer 1

Just took the test and got the correct answer. :)))

Explanation:

Look at the image down below!

Answer 2

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
