Order the sides of a triangle by their lengths when given information about the measures of the angles. (a)
The student, given information concerning the lengths of sides and/or measures of angles in triangles, will solve problems, including practical problems. This will include a) ordering the sides by length, given angle measures; b) ordering the angles by degree measure, given side lengths; c) determining whether a triangle exists; and d) determining the range in which the length of the third side must lie.
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to
