Triangle Properties

Angles

What is the sum of the interior angles of any triangle?
If angles 1 and 2 are 40 degrees and 60 degrees what is the missing interior angle? What is the measure of the exterior angle?

















Sides

What is the relationship between the sides of any triangle?   If side a is 8 centimeters, what is the length of sides b and c?  When we add two sides of the triangle how does the sum compare to the remaining side?
