An architect draws the incomplete picture of a house, as shown. He draws arcs at P and Q to construct a wall CD perpendicular to wall BC.

Which statement best describes the next step of the construction?

Join the points D and C using a straightedge.

Place the compass on point P and draw an arc below the line BT.

Draw an arc across QT from the point P.

Fix the compass at point T and draw an arc across QT

You can't just Join C-D....

You have to make sure ... That the line you draw from C is perpendicular to BC first.

dariyana · Answer

so the answer is A

paxpolaris · Answer

no .... i said it can't be A....

paxpolaris · Answer

@dariyana ?? you follow why?

dariyana · Answer

no not really @PaxPolaris

paxpolaris · Answer

you should
Place the compass on point P and draw an arc below the line BT. 

then Place the compass on point Q and draw an arc that meets the other arc you made... 

then pass a line through the point where they meet and C.

dariyana · Answer

lol i knew that so the answer wold be B correct

paxpolaris · Answer

then you will know for sure that the line you are drawing is perpendicular
