WHAT IS THE “RIGHT-BRAINED/LEFT-
BRAINED” ARGUMENT?
1/17/12WARM-UP
• There is not really an argument, but both sides of the brain process different information. Sometimes people say your are “one-brained dominant” because you tend to emulate the abilities of what that side of the brain controls.
• For example, left-brained people are good at logic and calculation, while right-brained people are better at spatial understanding.

• What is the difference between the circumcenter and the incenter?

• What is the difference between the circumcenter and the incenter?
• The circumcenter is the point of concurrency of the perpendicular bisectors and is equidistant from the vertices

• What is the difference between the circumcenter and the incenter?
• The circumcenter is the point of concurrency of the perpendicular bisectors and is equidistant from the vertices
• The incenter is the point of concurrency of the angle bisectors and is equidistant from the sides

• You drove to your cousin’s house, which is 460 miles away. After two hours, you had gone 100 miles. After 8 hours, you reached your destination. Write an equation that gives the number of miles you had driven, y, in terms of the number of hours you had driven, x.
