20 bucks a problem, bitches 
[Monday, May 30th, 2005] 
If two parallel lines are intersected by a transversal, then alternate interior angles are supplementary. (True or False)
If a quaderlateral is a parrellelagram, then consecutive angles are equal. (True or False)
If two parallel lines are intersected by a transveral, then cointerior are supplementary. (True or False)
If a quaderlaterl is a parellelagram, then opposite angles are supplementary. (True or False)
If a figure is a rhombus, then it is a parallelagram. A square is a rhombus, therefore a square is a parallelagram. (Valid or Invalid)
Write a true implication, write converse in an ifthen statement. Is it valid or invalid?
Is the biconditional "a quaderlateral is a square if and only if it is a rectangle" true or false?
valid or invalid: 15+2x=25 if and only if 2x=10 x is not equal to 5 therefore 2x is not equal to 10
given: 3x^240=8; x<0 prove: x= 4
1. 3x^240=8 1. given 2. 3x^2=48 2. 3. 3. division property of equality 4. x= +/4 4. 5 x<0 5. given 6. 6. or rule
write a paragraph proof: 5(2x3)=25, then x=4
write a 2 column proof:
given: m and n are parallel. transversal T intersects lines m and n prove: n < 1 = m <7
1.m is parallel to n; t intersects m and n 1. given 2. , <1 =m < 3; m <5 =m<7 3. m< 3= m <5 4. m <1 =m<5 5. m<1 = m<7
