Using scissors and a ruler, cut out a triangle from a piece of colored paper. Clean up your area afterwards. We will be using the triangle during our lesson today. . Constructing Triangles. Common Core 7.G.2. by basic rigid motions. A geometric realization of a proof in . H. Wu’s “Teaching Geometry According to the Common Core Standards”. Given two triangles, ABC and A. 0. B. 0. C. 0. .. Assume two pairs of equal corresponding sides with the angle between them equal.. A surd is a number which is written with a root sign and cannot be simplified e.g. . or . Trying to write down the exact number as a decimal is impossible because surds are irrational numbers and therefore the decimal part ‘continues forever’, without repeating.. 45-45-90 & 30-60-90.

Classify each triangle by its angle measures.. 1.. . . 2.. . 3. . Simplify . 4. . If . Hopefully, you remember these from last year (you were required to memorize ten of them) plus SOH CAH TOA.. If not, you need to know the reciprocal and quotient identities which are in the blue box on pg A17, and the Pythagorean, Addition, and Double-Angle Formulas which are inside the back cover of your books.. Pre-Course Reading Label the left side of your journal, “Chosen Quote" and label the right side, "Respond and Analyze." 2. The left side is where you will record quoted text and page numbers from the novel. Terminal side – end side of angle. Standard position – An angle whose initial side is on the positive x-axis. Positive angles. An angle in standard position that rotates counterclockwise. Negative angles. (50 minutes):. Target: I can draw triangles with specific criteria.. 5 minutes Warm-up (notebook). 25 minutes Launch video and model at least one construction (you may find that you need to model more, depending on the class – it’s really tough for them to put together all of these pieces.).
