Lines & Lengths Review

Match the following

• 1-dimensional

  Boundless length w/o width

• Line

• Subset of a line Bounded on 2 ends

• (Line) Segment

• 0-dimensional Bounded location w/o size

• Plane

• Subset of a line Bounded on 1 end

• Point

• 2-dimensional Boundless l & w

  w/o depth

• Ray

Simplify

Write an equation that correctly models the lengths shown.

• 2x + 20 + x + 21 = 9

• 2x + 20 + 9 = x + 21

• 9 + x + 21 = 2x + 20

• 2x + 20 - 9 = x + 21

Find AC

Find the midpoint of the line segment with the given endpoints (3,9) and (5,9)

• (-1,0)

• (4,9)

• (6,7)

• (7,9)

• Draw a circle centered at E with radius CD

• Draw a segment between the E and the prev. point

• Draw a line between the intersections of both circles

• Draw a point where the original and prev. lines intersect

• Draw a circle centered at one endpoint with a radius > 1/2 segment

• Draw a circle centered at other endpoint with a radius same as the prev.
