Questions:
1. How did you identify the postulate or theorem in part I?
2. How did you identify the additional part to prove that the two
triangles are congruent in Part II?
3. Were you able to give an additional congruent part in Part III to prove
that the two triangles are congruent? If yes, how?
A.
Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
