Key T3 Constructions

Autor:Ambi Bobmanuel

Instructions

  1. Use the Construction Protocol bar (located at the bottom right hand side of each Geogebra applet window) to fast-forward and rewind through the steps of a potential solution for the test.
  2. Check to see if the construction passes the drag test - drag vertices from the given information and watch how the construction changes.
 Your sketches will be graded on:
  • a. accuracy (did they do what was asked)
  • b. robustness (do they pass the drag test?)
  • c. efficiency (don’t make extra circles!)
  • d. style (Please measure relevant lengths, angles, etc). Color can make your sketch look good.
Below are sketches that hint at the final answer. Show all your circles and segments.

1. Given 2 side lengths that make up a given angle, construct a congruent triangle using side-angle-side.

2. Starting with a point floating above a line, construct a square.

3. Construct a 30-degree angle. Confirm with the measure tool.

4. Start with a short and a long segment. Construct a segment whose lenght is the a AVERAGE of the two given segment lengths. Confirm with the measure tool.
