Quiz next block over 4.1-3 (HW #6-8). This is not a difficult quiz. There will be a review worksheet for warm-up next time. There are no complicated "find the angle" problems on the quiz. There are no proofs or actual vocabulary. We will work more on the Triangle Inequalities before the quiz. There is a find-the-angles sketch on the quiz where isosceles is important. The quiz is 22 pts.
In class today we did a fill-in-the-blank proof of C-23: An exterior angle of a triangle has a measure that is the sum of its remote interior angles (pp 222-3).
We also figured out the triangle inequality rules: The sum of the side lengths of the two shorter sides of a triangle must be greater than the length of the longest side.
The largest angle in a triangle is opposite the longest side; the smallest angle is opposite the shortest side.
We did p 169:1 (constructions) to discover the Triangle Congruence Shortcut SSS (not on homework or quiz).
HW #8 - pp 223-4: 1-9, 12, 16-17, 19-20 and p 208:10-11.
Hint on p 208: 10 - You do not need to construct a triangle with these angles. You can add them on a ray; the leftover angle on the line will be the correct measure.
At the end of class, we worked on a review worksheet of 4.1-3. It will be completed and checked as a warm-up next block. (attached below).
