Solutions are made up of two non reacting species called solute and solvent. The amount of solute in solvent is known as concentration of that solute. Concentration is often measured in Molarity. Molarity is the amount of solute dissolved in 1 dm3 of solution. Answer to your question is as follow;
Answer:
(1) The two column proof is presented here as follows;
Statement Reasons
1. C is the midpoint of
Given
B is the midpoint of
D is the midpoint of
2. AC = CE, AB = BC, CD = DE Definition of midpoint
3. AB + BC = AC, CD + DE = CE Segment addition postulate
4. CD + DE = AC Substitution property of equality
5. AB + BC = CD + DE Substitution property of equality
6. BC + BC = CD + CD Substitution property of equality
7. 2·BC = 2·CD Addition of two identical quantities
8. BC = CD Division property of equality
9. BC ≅ CD Definition of Congruence
(2) The two column proof for the triangular geometric figure is presented here as follows;
Statement Reasons
1. 2·WV = XY; 2·YZ = XW; WV = YZ Given
2. 2·WV = 2·YZ Multiplication property
3. XY = XW Substitution Property
4. XW + WV = XV Segment Addition Property
XY + YZ = XZ
5. XW + WV = XV Substitution Property
XW + WV = XZ
6. XV = XZ Substitution Property
