You can measure the length of a curved line by using a flexible measuring tape following the curve or by breaking it down into smaller straight segments and adding them up. Another option is to use a formula that calculates the arc length of a curve based on its equation and limits.

To create a triangle using 3 shapes, you can use three line segments of equal length. Arrange the line segments so that they connect at their endpoints to form a closed shape with three sides. This shape will resemble a triangle, with three angles adding up to 180 degrees. Ensure that the line segments do not overlap or intersect each other to maintain the triangular shape.
You should use a tape measure, ruler, or meter stick. The measurements should be in inches, feet, or centimeters.
