Big take-away: this is not a "vocabulary" unit. This is about developing the symbolic language of geometry and connecting it to the verbal. The skills acquired lean more toward correct naming, good sketching, connecting definitions to sketches and interpreting what is true based on definitions.
We practiced naming and sketching of lines, segments, and rays from pp 33-34 in textbook: 2-6,8-11,13-16,18,21,22.
We added "Congruent segments" to our Geometric Truth and shared what good entries should look like. The definition and sketch is found on p 26 of your book (Segments are congruent if and only if...) Copy the triangle with the equal sides. We discussed what a congruent sign looks like and how to mark segments congruent.
We spent time with angles... make up a definition of angle based on a sketch. How do we name angles? What is an angle measure? How do we measure an angle with a protractor?
HW #4: pp 37: 1-14.
Add to Geometric Truth section from pp 34-37 (page, term, definition, sketch, label): angle measure, protractor, congruent angles, angle bisector. angle addition.
We also put "undefined terms" at the beginning of our Geometric Truth.
At the beginning of class, we took time on our phones to practice looking at the class website and finding pages in the online textbook.
Next time I will attach a copy of the Geometric Truth so far.
