Formulas Parallelogram: A = b*h Triangle: A = ½ b*h Trapezoid: A = ½ h(b1 + b2) Rhombus/Kite: A = ½ d1d2 Regular Polygons: A = ½ a*p Circumference: C = 2πr or πd Circle: A = πr2
Measure of Arc: mAB = angle measure Arc Length = mAB * 2πr (circumference of circle) 360 Sector: A = mAB * πr2 (area of circle) 360 Segment of circle: A = (area of sector) – (area of
triangle)

7-2: Pythagorean Theorem and Converse
In a right triangle, a2 + b2 = c2
If a2 + b2 = c2 => right triangle If a2 + b2 > c2 => acute triangle If a2 + b2 < c2 => obtuse triangle
