Applying coordinates to different geometrical scenarios

Given the endpoint and midpoint find the missing endpoint.

Endpoint: 10 Midpoint: 1 Endpoint:

Find the midpoint:

• A

• B

• C

• D

What is the formula for midpoint?

• 
• 
• 
• a²+b²=c²

Find the midpoint of the line segment with the given endpoint.

(-4,-2), (3,3)

• (-2,-2)

• (-5,7)

• (-.05,0.5)

• (3,2)

Answer explanation

Remember the midpoint formula.

In the line segment from A to B, The point A is (3, 0) and the Midpoint is (-3, 4). What are the coordinates of point D?

• (0, -2)

• (0, 2)

• (-9, 8)

• (-9, -8)

Find the y-coordinate of the midpoint of the line segment with the given endpoints (6,-6) and (-10,-10)

• -8

• -16

• -20

• 8

P (6, -1) and Q(2, 7) are the end points of a line segment PQ.

Determine the equation of the perpendicular bisector of PQ

Mid point of line segment joining points (-2 ,4) and (6, 10) is _____

• (2, 5)
• (2 , 7)
• (3 , 7)
• (3, 8)

Midpoint is a

• point in the middle of a line.

• pair of rays with the same endpoint that together create a straight line or angle

• point that divides a segment into 2 congruent parts.

• ray that divides an angle into two congruent angles

What is the midpoint between (10, 9)
and (-10, -5)

• (10, 2)
• (0, -2)
• (0, 2)
• (2, -2)
