Question

Triangle is rotated 180° around the origin. What will be the coordinates for Triangle J'K'L'? A(6,7)(6,2)(3,7)B(7,-6)(2,-7)(-3,-7)C(-6,-7)(-6,-2)(-3,-7)D(-7,6)(2,-6)(-7,3)

Answer 1

Answer:

A. (6,7)(6,2)(3,7)

Explanation:

From the graph, the coordinates of J, K and L are:

$J(-6,-7),K(-6,-2)\text{ and L}(-3,-7)$

When a point (x,y) is rotated 180° around the origin, we have the transformation rule:

$(x,y)\to(-x,-y)$

Therefore, the coordinates for Triangle J'K'L' are:

$J^{\prime}(6,7),K^{\prime}(6,2)\text{ and L'}(3,7)$

The correct choice is A.
