Question

Triangle EFG has vertices E(2,1), F (6,-1) and G (1,-5) find the points of EFG after 180 degrees rotation

Answer 1

Answer: The points of EFG after 180 degrees rotation will be : (-2,-1), (-6,1), (-1, 5).

Explanation:

Given: Triangle EFG has vertices E(2,1), F (6,-1) ,and G (1,-5).

According to 180 degrees rotation rule:

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

Image of E : (-2,-1)

Image of F = (-6,-(-1)) = (-6,1)

Image of G = (-1,-(-5)) = (-1, 5)

Hence, The points of EFG after 180 degrees rotation will be : (-2,-1), (-6,1), (-1, 5).
