QUIZ NEXT BLOCK!! Similar to review worksheet HW #15! Topics handed out in class today and attached below!
Having finished filling up our tool belt in the last block, today was devoted to two things: beginning to get the differences between different constructions into our heads AND working more with triangles, the big applications of constructions in our curriculum.
We began by entering C-7 (shortest distance) from p 161 into our Geometric Truth, as well as the definition of altitude (p 162). Be sure to copy good sketches. We practiced a 90 degree angle at a point on a line, using it to also construct a 45 and 135 (HW #14, problem 6). We also construct squares by two different methods (given one side, or given one diagonal), which also constructed parallel lines; constructed angle bisectors in triangles; discovered that points on the angle bisector are equidistant from the sides of the angle, allowing us to construct a circle that touches both sides of the angle.
A grade was taken on HW #13 for 4 pts.
Quiz topics were passed out, as well as homework #15 worksheet. Add to your worksheet: p 166: 4, 7-10, 12, 20-24. Topics and worksheet and answers are downloadable below.
We did an investigation together to discover C-8: Every point on the angle bisector of an angle is equidistant from the sides of the angle. This was done on patty paper. Can be glued into your geometric truth.
