Study Sheet 1.1.1 Study: Midpoint Formula Geometry Sem 2 Name: Date:, Use the questions below to keep track of key concepts from this lesson\'s study activity 1) Practice: Summarizing Fill in the blanks in the definition. The midpoint of a segment is the point between its two HORIZONTAL SEGMENTS 2) Practice: Making Mental Images and Summarizing The endpoints of a segment are (10, 0) and (20, 0). How do you know it is a horizontal segment? 3) Practice: Organizing Information and Summarizing Fill in the blanks to complete the list Midpoint of Horizontal Segment average of -coordinates of endpoints -coordinate coordinate-coordinates of endpoints 4) Practice: Making Mental Images Find the midpoint of each segment. Show your work. 1. Segment endpoints: (0, 0) and (20, 0) 2. Segment endpoints: (-10,0) and (20, 0) midpoint = midpoint

Solution

1) The midpoint of a segment is the point on the segment between its two endpoints.

2) Both the given points lie on X - axis, since the Y - coordinate is zero. So it is a horizontal segment.

3) X - coordinate = average of X - coordinates of endpoints.

Y - coordinate = average of Y - coordinates of endpoints.

4) 1) answer : (10,0)

2) answer : (5,0).
