Question

reflect the triangle FGH across the x-axis,what are the signs of the coordinates of triangle F'G'H'

Answer 1

Explanation

Step 1

check the coordinates of the triangle FGH

we have for all points

$\begin{gathered} negative\text{ x coordinate } \\ negative\text{ y coordinate} \\ \lparen-x,-y) \end{gathered}$

Step 2

now ,reflect across the x-axis :The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.so

$\begin{gathered} \lparen-x,-y)\Rightarrow reflection\text{ across-x-xis}\Rightarrow\lparen-x,-\left(-y\right)) \\ \end{gathered}$

so, the coordinates would be

$undefined$
