Geometry, Chapter 4: Congruent Triangles Learning Targets Standards: OACS‐ Indicators: Geometry and Spatial Sense Gr. 10 #1, 3‐5 CCS‐ G.CO.8, 10, 13; G.SRT.5 Nouns: What will students need to know? Triangle, vertex, adjacent, leg, hypotenuse, base, equilateral, isosceles, scalene, equiangular, acute, obtuse, right, interior angles, exterior angles, congruent, corresponding sides, corresponding angles, Side Side Side, Angle Angle Side, Angle Side Angle, Side Angle Side, Corresponding Parts of Congruent Triangles are Congruent, base angles, vertex angles Verbs: What will students be able to do? Describe, identify, label, name, recognize, explain, predict, differentiate, critique, justify, solve, apply, connect, construct Teacher Knowledge: Any implied knowledge or words that need clarified for student success. Students will need to know how to solve for x (taught in previous sections and last year in Algebra 1). Also, they will need to use ideas from the last two chapters in order to prove two triangles are congruent. Learning Targets (KRSP): I can…… 1. Name a triangle by its sides and angles, identify parts of an isosceles and right triangle, and identify exterior and interior angles of a triangle. 2. Solve problems with isosceles, equilateral and right triangles using the base‐angle theorem. 3. Solve problems involving triangle sum theorem and exterior angle theorem. 4. Recognize congruent figures and solve for missing sides and angles. 5. Prove two triangles are congruent by using SSS, SAS, ASA, AAS, hypotenuse‐leg and CPCTC; 6. Construct equilateral triangles.
