Plz helpp Statement 2)
A)Addition property
B) Definition of midpoint
C) Definition of equality
D) Segment addition postulate

Reason 6)
A) Subtraction property
B) Transitive property
C) Property of equality
D) Definition of congruence

Addition Property of EqualityIf AB = CD then AB + BC = BC +CD

Subtraction Property of EqualityIf AB + BC = BC + CD then AB = CD

Multiplication Property of EqualityIf m∢A = 90 then 2(m∢A) = 180

Division Property of EqualiityIf 2(m∢B) = 180 then m∢B = 90

Substitution PropertyIf m∢A + m∢B =180 and m∢B then m∢A + 90 =180

Distributive PropertyAB + AB = 2AB

Reflexive Propertym∢B = m∢B

Symmetric PropertyIf AB + BC = AC then AC = AB + BC

Transitive PropertyIf AB ≅ BC and BC ≅ CD then AB ≅ CD

Segment Addition PostulateIf C is between B and D, then BC + CD = BD

Angle Addition PostulateIf D is a point in the interior of ∢ABC then m∢ABD + m∢DBC = m∢ABC

Linear Pair PostulateIf two angles form a linear pair, then they are supplementary

Definition of Right AngleIf ∢B is a right angle then m∢B = 90

Definition of MidpointIf P is the midpoint of segment AB then AP =PB

Definition of Segment BisectorIf k intersects segment AB at M the Midpoint then k bisects segment AB

Definition of Perpendicular LinesIf two lines are ⊥ they form right angles

Definition of Congruent SegmentsIf AB = CD then segment AB ≅ segment CD

Definition of Congruent AnglesIf ∡A ≅∡ B then m∡A=m∡B

Definition of Angle BisectorIf ray AB bisects ∡CAD then∡ CAB ≅ ∡ BAD

Definition of Complementary AnglesIf ∡ Z and ∡Y are complementary m∡Z +m∡Y =90

Definition of Supplementary AnglesIf ∡ S and ∡T are supplementary m∡S +m∡T = 180

Step-by-step explanation:

step-by-step explanation:

b and c

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
