The sides of an equilateral triangle measure 16 inches. the midpoints of the sides of the triangle are joined to form another equilateral triangle with sides that are half the length of the outer triangle. this process is continued until three triangles are inscribed in the first triangle. the sum of the perimeters of all four triangles is inches.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

yes because they have the same amount of green and blur marbles.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
