Look at the figure
AB and A'B' are corresponding sides
A and A' are corresponding points
B and B' are corresponding points
In this problem the big figure and the small figure are similar
that means
The corresponding sides are proportional
To find out the scale factor
divide A'C'/AC
we havr
A'C'=1 unit
AC=4 units
substitute
1/4=0.25
the scale factor is 0.25
is less than 1 so
is a reduction
Part 3
Figure B is the small figure
Figure A is the big figure or original figure
so
Verify each options
Option A is not true
Because figure B is not larger than figure A
Option B
The option B is true
because the figures are similar, the number of edges and the number of angles is the same
Option C
The option C is not true
The perimeter of figure A is greater than perimeter of figure B
Option D
The option D is true
because the figures are similar, the number of edges and the number
of angles is the same
Option E
The option E is true
Because, if two figures are similar, then the corresponding angles are congruent and the corresponding sides are proportional
