If > Then, Hypothesis > Conclusion

EX : If you live in Nashville then you live in Tennessee

Inverse - ~P > ~Q

Converse - Q > P

Contrapositive - ~Q > ~P

If it is Saturday, then there's no school

Inverse - If it's not Saturday, then there's no school F

Converse - If there's no school, then it's Saturday F

Contrapositive - If there is school, then it's not Saturday T

Biconditional Statements - (P>Q) ^ (A>P)

P > Q - Circle inside circle

Parallel - Lines that never cross

Perpendicular - Opposite Reciprocals

EX : 3/4, 3/4, / 2/5, -5/2

(X2 -X1) , (Y2- Y1)

# data[].attributes.body
Point Slope - (Y2 - Y1) = M(X2 - X1)

EX : (4, 1) Slope = 2

Y - 1 = 2(X - 4)

Standard - Ax + By = C

Slope Intercept - Y = mx + b

EX : 5X + 2Y = -2

Y = -5/2x - 1

EX : 2X - 4Y = 28

Y = 1/2X - 7

X - Midsegment of triangle x2 = Both upper and lower leg combined

EX : If AB = 14 and DC = 26, find EF

EF = 14+26/2

EF = 20

EX : If EF = 22 and DC = 38, find AB
