Copy of Bisect This (Part 1)
1.5.3 Part 1
1. Estimate the location of a point, D, so that angle DBA is approximately congruent to angle CBD. 2. Measure angles DBA and CBD with the angle measurement tool. 3. Check your results by doing a DRAG TEST. (This is where you try to drag each of the points. If the construction stays true, it works; if the construction doesn't stay true, it fails and is not a good construction.)
When you create ray BD in this manner, you see that ray BD is NOT a true angle bisector. Explain in sentences why this method doesn't work. Sentence Frame: "This method doesn't work because ___."
