Figure B is a scaled copy of Figure A. Figure A
Figure B
What is the scale factor from Figure A to Figure B?

Scale factor = 3 : 1

Step-by-step explanation:

Scale factor of figure =

From the graph attached,

Scale factor =

                    = [Since size of every square of the graph is same]

                    = 3

Therefore, scale factor of figure A to figure B is 3.

In other words ratio of the size of figure A to figure B will be 3 : 1.

f is the midpoint of

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
