Exercise 24.9 End of chapter exercises

Complete the following on the Cartesian plane:

  1. Draw \(\triangle KLM\) with vertices \(K(-5; 0)\), \(L(-5; 3)\) and \(M(0; 3)\).

  2. Draw \(\triangle K'L'M'\), the image of \(\triangle KLM\) rotated by \(180°\) in a clockwise direction about the origin.

Draw the following on the Cartesian plane:

  1. Plot \(\triangle ABC\) with vertices \(A(-2; 0)\), \(B(0; 5)\) and \(C(0; 0)\).

  2. Draw \(\triangle A'B'C'\), the image of \(\triangle ABC\) rotated by \(90°\) in an anti-clockwise direction about the origin.

Describe the rotation transformation.

\(\triangle P'Q'R'\) is the image of \(\triangle PQR\) rotated by \(90°\) in a clockwise direction about the origin.

\(\triangle R'S'T'\) is the image of \(\triangle RST\) rotated by \(180°\) in a clockwise (or anti-clockwise) direction about the origin.
