Peruse Theorem 78 and 79 on your handout

1
INTRODUCTION TO SPECIAL RIGHT
TRIANGLES!!!

• Peruse Theorem 7-8 and 7-9 on your handout
• Notice the RATIO VALUE for each side of these
  special right triangles

2
3 STEPS TO SUCCESS FOR SPECIAL RIGHT TRIANGLES!!!

• Put the X values on their proper spot
• Solve for X
• Substitute the X value into the missing sides
