In a classroom, a projector is placed to explain about midsegments, a student of height 4 feet is standing in between the projector and the wall on which the projection is made. The edge of a projector light reaches the top of his head. What is the height of his shadow?
- 4
- 8
- 6
- 2
Hint:
the midpoint theorem refers to the midpoint of the line segment. It defines the coordinate points of the midpoint of the line segment and can be found by taking the average of the coordinates of the given endpoints.
The correct answer is: 8
From the given data and the figure, DE is a midsegment of the triangle ABC.
We apply the midsegment theorem,
Given DE = 4 feet
Shadow = BC = 2DE = 
= 8 feet.
