Question

spiral review reflect the triangle across the y - axis and draw the image. use the polygon tool to draw the image.

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ across the $y$-axis, the new point is $(-x,y)$.

Step2: Identify original vertices

Let the vertices of the original triangle be $(x_1,y_1)$, $(x_2,y_2)$, $(x_3,y_3)$. Suppose the vertices are $(-6,6)$, $(-2,8)$, $(-4,2)$.

Step3: Calculate new vertices

For $(-6,6)$, the new vertex is $(6,6)$. For $(-2,8)$, the new vertex is $(2,8)$. For $(-4,2)$, the new vertex is $(4,2)$.

Step4: Draw the new triangle

Use the Polygon Tool to plot the points $(6,6)$, $(2,8)$, $(4,2)$ and connect them to form the reflected triangle.

Answer:

Use the Polygon Tool to plot vertices $(6,6)$, $(2,8)$, $(4,2)$ and draw the triangle.
