• 1. Geometry drill 1/8/13Warm UpClassify each triangle by its angle measures.1. 2. acute right3. Simplify 124. If a = 6, b = 7, and c = 12, find a2 + b2 and find c2.Which value is greater? 85; 144; c2
• 2. ObjectiveSW define and apply thePythagorean Theoremso that they can find thedimensions of geometricfigures.
• 3. Right Triangle Def.Legs-__________ c a
• 4. Right Triangle Def.Legs-__________ a and b c a
• 5. Right Triangle Def.Legs-__________ a and bHypotenuse-______ c a
• 6. Right Triangle Def.Legs-__________ a and bHypotenuse-______ c c a
• 7. Hypotenuse The ________ side of a right triangle across from the ________ angle.
• 8. Hypotenuse The ________ side of longest a right triangle across from the ________ right angle.
• 9. PythagoreanTheorem triangle, For any rightthe sum of the squareof the two ___is equal tothe square a cof the_________.
• 10. PythagoreanTheorem triangle, For any rightthe sum of the squareof the two legs ___is equal tothe square a cof the_________. hypotenuse
• 11. PythagoreanTheorema +b =c 2 2 2 c a b
• 12. Corollary to thePythagoreanTheoremIf the sum of the squaresof the two shorter sidesof a triangle is less thanthe square of the longestside, then the triangle is______.
• 13. Corollary to thePythagoreanTheoremIf the sum of the squaresof the two shorter sidesof a triangle is less thanthe square of the longestside, then the triangle is______. obtuse
• 14. Corollary to thePythagoreanTheoremIf the sum of the squaresof the two shorter sidesof a triangle is greaterthan the square of thelongest side, then thetriangle is ______.
• 15. Corollary to thePythagoreanTheoremIf the sum of the squaresof the two shorter sidesof a triangle is greaterthan the square of thelongest side, then thetriangle is ______. acute
• 16. Corollary to thePythagoreanTheoremIf the sum of the squaresof the two shorter sidesof a triangle is equal tothe square of the longestside, then the triangle is______.
• 17. Corollary to thePythagoreanTheoremIf the sum of the squaresof the two shorter sidesof a triangle is equal tothe square of the longestside, then the triangle is______. right
• 18. Corollary to thePythagoreanTheorema +b >c acute 2 2 2a +b <c 2 2 2 obtusea +b =c 2 2 2 right
