Lesson 3: Practice Problems

Problem 1

Apply each transformation described to Figure A. If you get stuck, try using tracing paper.

  1. A translation which takes to

    Blue parallelogram A with point P in the upper right corner. A line l is marked and a point P' is on the other side of line l.
  2. A counterclockwise rotation of A, using center , of 60 degrees

    Blue parallelogram A with point P in the upper right corner. A line l is marked and a point P' is on the other side of line l.
  3. A reflection of A across line

    Blue parallelogram A with point P in the upper right corner. A line l is marked and a point P' is on the other side of line l.

Problem 2

Here is triangle drawn on a grid.

On the grid, draw a rotation of triangle , a translation of triangle , and a reflection of triangle . Describe clearly how each was done.

A triangle, ABC on a grid.

Problem 3 From Unit 1 Lesson 2

  1. Draw the translated image of so that vertex moves to . Tracing paper may be useful.

    A pentagon, ABCDE. There is a point C" to the right of ABCDE.
  2. Draw the reflected image of Pentagon with line of reflection . Tracing paper may be useful.

    A pentagon, ABCDE, with line of reflection l vertically on the right side of ABCDE.
  3. Draw the rotation of Pentagon around clockwise by an angle of 150 degrees. Tracing paper and a protractor may be useful.

    A pentagon, ABCDE.
