5.3 - Triangle Inequalities (sides, angles)
In this investigation, you will explore the relationships among the sides and angles of a triangle.
Play around with the applet by moving the vertices of the purple triangle. Make the purple triangle scalene before moving on to the questions below.
1. Find the largest angle in the purple triangle. Where is the largest purple side in relation to this angle?
2. Find the smallest angle in the green triangle. Where is the smallest green side in relation to this angle?
3. Find the medium side in the red triangle. Where is the medium red angle in relation to this side?
4. List the orange angles from least to greatest.
