Question

The coordinates of the vertices of triangle 1 are A(6,6),B(12,9),C(9,6). Reflect triangle1, across the x-axis

Answer 1

Given the cordinates of the vertices of a triangle :

A(6,6), B(12,9), C(9,6).

A reflection across the x-axis implies that the x-cordinates of the vertices remain the same, while the y-cordinates take negative values.

The new cordinates of the vertices after reflection :

A(6, -6), B(12, -9), C(9, -6)
