Please assist me with these 2 columns proof part 2.​
DENIUS [597]

Answer:

Step-by-step explanation:

I have to say that there is not enough givens to prove anything. If the statement given is all there is, then many things can be proven.

One

All you are given is that the diagonal is bisected. It does not mean that the other diagonal is bisected without more information. All you can prove is that DH = HF                   Definition of a midpoint.

Two

For the second one KO bisects JKM. What that means is that the two smaller angles are equal. Bisects means cuts in half.

JKO = KOM. KO cuts JKM in half The reason is definition of bisect.

Three

This one actually can prove some something.

AB = BC   which equals AC

BC = CD  which equals BD

Therefore AC = DB

This is the associative property of equality. So far it is the hardest one.

Four

DE perpendicular to EF

Join DF                                                A triangle is formed by construction.

Triangle DEF   if s a right triangle.     Perpendiculars form right angles.
