Question

Triangle DEF with vertices D(2, 6), E(5, 6)and F(5, 1). Write the coordinates of triangle D’E’F’ after a

reflection over the y-axis.

Answer 1

The coordinates of triangle after reflection over y-axis

D¹( -2 ,6) , E¹( -5 ,6) , F¹ (-5,1)

Explanation:

Explanation:-

Given that DEF with vertices D(2,6), E(5,6), and F(5,1)

Given that the triangle DEF reflection over the 'y' - axis then transformed into

( x,y) → (-x,y)

Now,

D(2,6) → D¹( -2 ,6)

E(5,6)→ E¹( -5 ,6)

F(5,1)→ F¹ (-5,1)

Final answer:-

The coordinates of triangle after reflection over y-axis

D¹( -2 ,6) , E¹( -5 ,6) , F¹ (-5,1)
