Construct the rotation of ∆ABC about point P, by ∠ RST[br][br]Using angle measurement, create angle with given size, and create polygon. You will be able to walk through the construction of a rotation. By the end of this exercise you should be able to explain how to complete the construction with paper, a pencil, and a compass.

[i][b]Using the following steps, construct the rotation of ∆ABC about point P, by ∠ RST[/b][/i][br][br]1. Using the Angle Measurement tool (shown below) find the measure of ∠ RST: _____[br]* Choose vertices clockwise R → S → T[br] [br]2. Select Create Angle with Given Size from the Drop-Down Menu. (shown below)[br]Select Point A, select the Center of Rotation (point P), [br]and input the angle of rotation (from in question 1)[br]What is the name of the new point created? _______[br][br]3. Select Create Angle with Given Size from the Drop-Down Menu.[br]Select Point B, select the Center of Rotation, and input the angle of rotation [br]What is the name of the new point created? _______[br][br]4. Select Create Angle with Given Size from the Drop-Down Menu.[br]Select point C, select the Center of Rotation, and input the angle of rotation[br]What is the name of the new point created? _______[br][br]5. Using the Polygon tool, connect points A’, B’, C’. (And back to A’)[br] [br][br][i]Write steps to construct the rotation of ∆ABC about point P, by ∠ RST on paper using a compass.[/i]
