• It has 2 dimensions.

• It has 1 dimension.

• It has infinite length, no width, no height.

• It is represented by a capital letter.

• It has at least 2 points .

Select all that applies to describe a plane.

• It has 2 dimensions.

• It is represented by 3 non-collinear points.

• It has at least 2 distinct points.

• It has length, width but no height.

• It has infinite length and width.

Find the midpoint.

Find the other endpoint of the line segment with the given endpoint (1,-9) and midpoint (-9,3)

• (-19,15)

• (5,-6)

• (-4,-3)

• (6,2)

Find the measure of PQ

• PQ=4

• PQ=2

• PQ=8

• PQ=16

Find the length indicated.

Write an equation that correctly models the lengths shown.

• 2x + 20 + x + 21 = 9

• 9 + x + 21 = 2x + 20

• 2x + 20 + 9 = x + 21

• 2x + 20 - 9 = x + 21
