Check for Understanding
1.
Align the 0 point on the ruler with the leftmost
endpoint of the segment. Align the edge of the
ruler along the segment. Note where the
rightmost endpoint falls on the scale and read
the closest eighth of an inch measurement.
2.
Sample answers: rectangle, square, equilateral
triangle
3.
Each inch on the ruler is divided into eighths.
Point

The long marks on the ruler are centimeters, and
the shorter marks are millimeters. There are
10 millimeters for each centimeter. Thus, the bee
is 13 millimeters or 1.3 centimeters long.
