Question

Triangle ABC with coordinates A (3,-2), B (5,5), and C (-4, 2) is reflected across
the x-axis. State the coordinates of the resulting triangle, A'B'C.

Answer 1

Step-by-step explanation:

the formula of coordinates (x, y) that reflected across the x-axis : (x, y) => (x, -y)

so,

A(3, -2) => A'(3, 2)

B(5, 5) => B'(5, -5)

C(-4, 2) => C'(-4, -2)

Answer 2

Coordinates of ∆ABC

• A(3,-2)
• B(5,5)
• C(-4,2)

Now co-ordibates of ∆A'B'C'

$\\ \rm\longmapsto A'=(3,2)$

$\\ \rm\longmapsto B'=(5,-5)$

$\\ \rm\longmapsto C'=(-4,-2)$
