1) How do you find the area of a triangle? 2) How do you find the perimeter of a triangle? 3) How do you find the area of a trapezoid? What is the formula? 4) I find this formula particularly challenging to remember. Instead, I think of it as A=(Mean of bases)(height). Explain how that is the same thing as your formula above. 5) What is pi? 6) What does circumference mean? How do you find it? 7) How can you find the area of a circle?

1) (base*height)/2 2) 2p=side1+side2+side3 3) Area= ((Base1+Base2)/2)*Height 4) It is the same thing because the mean of two numbers is their sum divided by two 5) pi is the ratio between the circumference of a circle and its diameter 6) I'd say it's the boundary of a circle, the formula is (diameter*pi) or (2range*pi) 7) pi*(range^2)
