Question

The figure below shows a trapezoid, ABCD, having side AB parallel to side DC. The diagonals AC and BD intersect at point O.


If the length of AO is three times the length of CO, the length of DC is

three times the length of OC
three times the length of DO
one-third of the length of AC
one-third of the length of AB

Im gonna post the picture

hm ok hope its correct

Answer 15

@Badsheep

Answer 16

i have one more question after this also

Answer 17

i think AOB and DOC are similar triangles therefore all the lengths are proportionate and "double the length of AO" is correct

Answer 18

So B is correct? also i have one more question if ur not busy

Answer 19

I need to draw this to scale. It might take awhile. I think it is either C or D.

Answer 20

ohh so no B?

Answer 21

Look at the figure below:


Based on the figure, which pair of triangles is congruent by the Side Angle Side Postulate?

Triangle ABD and triangle ECD
Triangle ABC and triangle ECD
Triangle ABD and triangle ADC
Triangle ADC and triangle ABC

Answer 22

thats the last Q

Answer 23

anyone there?

Answer 24

Bea and dec, be and de are congruent, of course angle e and e are congruent and ea and ec are congruent

Answer 25

The answer to the first question is D.

Answer 26

Your second question makes no sense at all. Your drawing does not show a triangle BEA, since there isn't a line segment BE. I don't see an angle e and e are congruent???? No sense at all. Sorry I'm out.

Answer 27

i didn't make the question. My TEACHER did or whoever, not ME. I don't control how the question is. It obviously makes sense. You just don't get it.
