(1) The two column proof is presented here as follows;

Statement Reasons

1. C is the midpoint of $\overline {AE}$ Given

B is the midpoint of $\overline {AC}$

D is the midpoint of $\overline {CE}$

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

Answer from: Quest

dishwashers don't have rights

explanation:

dishwashers are meant for one thing and one thing only: dishwashing. they belong in the kitchen making sandwiches and cleaning up for the man of their household. if your dishwasher starts acting up just slap it and wait a minute.

Answer from: Quest

a solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. the solution is homogeneous and does not settle out. a colloid is intermediate between asolution and a suspension. while asuspension will separate out a colloid will not.

What’s is a suspension, and how is it different from a solution?

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
