Construction of Triangles using given Criteria

After learning types of angles and triangles, 4th graders get ready to learn constructing triangles. We need a ruler and a protractor to construct any triangle from given classification.

Keep in mind that the starting point is always drawing the horizontal arm of the angle (of the required length according to the given classification). Then start to construct angles (if in the criteria) on this base line.

Below are the activity sheets on the concept;

After doing the above exercise can you construct another triangle with a side length of 7in and two angles of 50 degrees and 40 degrees.
