Theorem
What is a triangle
Is formed by line segments that intersect only at their end points
What is an interior angle
The angle formed by the segments that lies inside the triangle is an interior angle
What is an exterior angle
Formed by one side of the triangle has tow remote interior angles
What are legs?
Are the sides that form the right angle
What is the hypotenuse?
Is the opposite the right angle it is the logistics side of the triangle
The Pythagorean theorem is __________
Dis rides the relation ship beetween the lengths of legs and the hypotenuse for any right triangle
What is a converse
If you reverse the Pythagorean theorem you get its converse
