Pythagorean Theorem Converse Special Triangles
Pythagorean Theorem What do you remember? Right Triangles Hypotenuse – longest side Legs – two shorter sides
Right Triangle Hypotenuse = c Legs are a and b Remember how to determine which leg will be longer longer leg across from larger angle
Type of Triangle We also discussed other types of triangles that could be formed using a version of Pythagoreans Theorem
Example
Special Right Triangles Isosceles Right Triangle Two sides are congruent Two angles are congruent Can you prove this
Proof
Special Right Triangle Short leg across from 30 Long leg across from 60 Hypotenuse across from 90
