Math CC7/8 – Be Prepared On Desk: Learning Log: 1. Pencil • HW: p. 76 #6,7,8,9 & Parent 2. Math Journal sig. on Quiz Tracking Sheet 3. Learning Log • Pass back Quiz – Quiz Retake: Mon. 9/26 in class • SD Test Wed. 9/28 Picture Day –Tues. 9/27 during Math Fundraiser – Keep selling! Tasks for Today • Pass back Quiz – Tracking Sheet: Parent Sig. by Friday? – Quiz Retake: Monday 9/26 • SD Lesson 3.2 A-D • Begin HW? Quiz Procedures • Look at your score – add to LL – Parent Signature on Quiz Tracking Sheet prior to Quiz Retake – Retakes: • Must have parent sig. on Tracking Sheet • Retake missed sections only • Retake must be returned with 1st Quiz to teacher before grade is adjusted Launch video 3.2 These SSA won’t create a unique triangle, but some such combinations will. AAA won’t make a congruent triangle, the side lengths may be different.(similar triangle) AAS will make a unique triangle because we know the third angle must be 180-106 degrees. (ASA situation) Use labsheet 3.2B • Draw an equilateral triangle with sides 1 inch. • Draw an angle of 60 degrees and mark 2 sides of 1 inch on the legs of that angle. Then connect the end points. • Draw a right triangle with legs 1 inch and 1.25 inches. • Draw an angle of 90 degrees and mark sides of 1 in. and 1.25 in on the legs of that angle. Then connect the end points. Use labsheet 3.2B • You need to give either 2 sides and the included angle, or 2 angles and the side. • Angles = 30, 125, 25 degrees • Sides = 1.25, 1.25, and 2.5 inches • Draw an isosceles triangle with vertex angle 40 degrees and equal sides 1.5 in long. • Draw an isosceles triangle with base 1 in. long and base angles 70 degrees. You need at least 3 sides and/or angle measurements, but not ANY three. • Given SSS - there will only be one triangle. • Given 2 angles and one side length (either the included side (ASA) or the nonincluded side (AAS)), there will be only ONE triangle. All copies of the right triangle using the same 3 sides lengths will make the same triangle. The order in which you connect the sides does NOT matter. So, the copy will also be a right triangle.
