"Use concepts and theorems relating to congruence and similarity of triangles to solve problems."
"Know and directly apply relevant theorems such as the: • triangle angle sum theorem."
What you'll learn
- Solve for unknown angles and sides in isosceles and equilateral triangles, alone and inside larger figures, including when they are given as algebraic expressions
- Apply the base angles theorem: if two sides of a triangle are equal, the angles opposite those sides are equal
- Use the converse: if two angles of a triangle are equal, the sides opposite those angles are equal
- Use the facts that an equilateral triangle has three 60° angles and three equal sides, each implying the other
