Construction Tutorials

Below is a list of the constructions that will be included on the Construction Journal. Click on the video demonstration for each construction to get extra help on how to complete the construction. Video demonstrations for constructions that we have not covered yet will be added as we get to them in class.

Construction 1: I can duplicate a segment. Video demonstration

Construction 2: I can construct a perpendicular bisector and label the midpoint. Video demonstration

Construction 3: I can construct a perpendicular from a point to a line. Video demonstration

Construction 4: I can construct a perpendicular from a point on a line. Video demonstration

Construction 5: I can construct parallel lines. Video demonstration
Note: This is just one method for constructing parallel lines. Other methods were discussed in class.

Construction 6: I can duplicate an angle. Video demonstration

Construction 7: I can construct an angle bisector. Video demonstration

Construction 8: I can classify, define, and construct triangles:
Construction of an isosceles triangle. Video demonstration
Construction of an equilateral triangle. Video demonstration
Note: These are just two possible constructions of triangles. Other methods were discussed in class.

Construction 9: I can construction the points of concurrency:
I can construct the incenter. Video demonstration
I can construct the circumcenter. Video demonstration
I can construct the orthocenter. Video demonstration
I can construct the centroid. Video demonstration
