Big Ideas: The size of the side measurements of a triangle correspond with the angle measurements of that triangle. Three different triangles can be created using three angles and one side measure. Students have learned how to create triangles when all angles or all sides are known. In this lesson, students will be exploring how to construct triangles with three angles and one side measure. Students will once again focus on the possibility of constructing more than one triangle when given specific conditions. During this lesson, students will develop an understanding of the relationship between side lengths and angles. Vocabulary: acute triangle, obtuse triangle, right triangle, scalene triangle, isosceles triangle, equilateral triangle Special Materials: Rulers, Protractors, and Compasses
