Geometry for Teachers. Von Christopher G. Chua, LPT, MST. Instructor, Geometry for Teachers. Chapter Objectives. For this chapter in the course on Statistical Methods, graduate students are expected to develop the following learning competencies:. 4.2. SSS Postulate (Just call it SSS). If . three sides of one triangle . are congruent to. three sides of another triangle, . then the triangles are congruent.. SAS Postulate (Just call it SAS). If . A. . = . B. . C. . D. . = .  . Warm-Up. ~Write one sentence explaining what answer you chose.. ~Write one sentence explaining what answers you were able to eliminate.. Polygons and Triangles. The word polygon means many (poly) angles (gon). This includes triangles, squares, rectangles, trapezoids, parallelograms, . Side-Angle-Side (SAS) Congruence Postulate. If two sides and the included angle are congruent to the corresponding sides and angles on another triangle, then the triangles are congruent. . EXAMPLE 1. Review: . Midsegment. Theorem. Review: . Midsegment. Theorem. See the two triangles:. What if we compared corresponding sides with proportions?. 40x = 2560. x = 64.  . This is today’s lesson!. Using properties of perpendicular bisectors and angle bisectors. Perpendicular bisectors. What do we know about the right triangles formed when we draw an isosceles triangle that has a bisector of its vertex angle?. They are shapes with all straight sides. You’ve got triangles and squares. You’ve got . rhombuses . and hexagons. Just know that circles are not there.. I want to talk parallelograms!. They’ve got 2 pairs of parallel sides. Talya Eden, .
