When constructing an equilateral triangle by hand, which step comes after constructing a circle?

set compass to the diameter of the circle.
set compass to the radius of the circle.
use a straightedge to draw a diameter of the circle.
use a straightedge to draw the radius of the circle.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

false

inverse variation is not exponential

one triangle is 2.5 times bigger than the other triangle.
