## Introduction to Activity

Every triangle is made of six parts: three sides and three angles. Proving two triangles are congruent requires only three of those six parts.
Below is a pre-made triangle: ABC.
Objective: Take any three parts of the triangle, and attempt to create a triangle with the three parts. Answer the two questions below for each combination of parts you given.

## Operating the Geogebra Workspace

1) Each point labeled A regardless of subscript corresponds to point A in ABC. The same is true for all of the Bs and Cs.
2) Using the points on the line segments, you can either rotate the segment around a point or pick up the whole segment.
3) All the segments of the angles can be extended or shortened as needed.

## 1. Creating Congruent Triangles

Using any combination of **three** parts of the triangle, answer the following questions for each combination you attempt.
1. Can you create a congruent triangle with your parts?
2. Can you create a different triangle with your parts?
List all of the combinations which you can answer yes to number 1 and no to number 2 in the space provided.
