Answer:
equilateral triangle 3 3 perpendicular bisectors of the sides
regular heptagon 7 7 perpendicular bisectors of the sides
regular octagon 8 4 (perpendicular bisectors and 4 lines joining pairs of opposite vertices)
Step-by-step explanation:I got you
The value of x is: 
<u><em>Recall</em></u>:
Perimeter of a shape is the sum of all its sides
<em>Thus</em>:
Perimeter of the triangle = 
Perimeter of the rectangle = 
We are told that the perimeter of both shapes are equal. Set both perimeters equal and solve for x.
<em>Add like terms</em>

Answer:
scale factor = 1/2
Step-by-step explanation:
for AC: 4 + 4 = 8
8 is the AC of the red triangle
4 is the AC of the blue triangle
to get from 8 to 4, we divide by 2 or multiply by 1/2 (they mean the same thing)
10 is the CB of the red triangle
5 is the CB of the blue triangle
to get from 10 to 5, we divide by 2 or multiply by 1/2
