Chapter 4: Q15. (page 179)

For exercises 15-17, use the following information
The vertices of $螖 A B C$ are $A (0, 2), B (1.5, - 1.5), and C (- 2.5, 0)$ . The triangle is dilated so that its perimeter is three times the original perimeter.
15. Write the coordinates for $螖 A B C$ in a vertex matrix

Short Answer

Expert verified

Coordinates of triangle $A B C$ in vertex matrix is $[\begin{matrix} 0 & 1.5 & - 2.5 \\ 2 & - 1.5 & 0 \end{matrix}]$

Step by step solution

- Vertex matrix

An ordered pair $(x, y)$ is represented by a column matrix $[\begin{matrix} x \\ y \end{matrix}]$ which is known as vertex matrix of an ordered pair.

- Vertex matrix of a triangle

Since, a triangle has 3 ordered pair on vertices so required matrix has 2 rows and 3 columns.

First row represent $x - coordinate$ and second row represents $y - coordinate$ of each vertex.

- Required vertex matrix

As coordinates of the vertices of triangle are $A (0, 2), B (1.5, - 1.5), and C (- 2.5, 0)$

Write each ordered pair of triangle as a column of a matrix to get

$[\begin{matrix} 0 & 1.5 & 鈭� 2.5 \\ 2 & 鈭� 1.5 & 0 \end{matrix}]$
