(a)
To calculate : The coordinates of
The coordinates of
Given information :
A triangular sail is being ordered for sailboat. It is planned to sew a thin decorative strip connecting the midpoints
Formula used:
The coordinates of the midpoint
Calculation :
In the given figure,
So, the coordinates of
Therefore, the coordinates of
(b)
To calculate : The length of the strip and of the sail’s base.
The length of the strip is
Hence, the length of the strip is half of the length of the sail’s base.
Given information :
A triangular sail is being ordered for sailboat. It is planned to sew a thin decorative strip connecting the midpoints
Formula used:
The distance
Calculation :
The coordinates of
The length of the strip will be the distance between
The length of the sail’s base will be the distance between
Therefore, the length of the strip is
(c)
To explain : The length of the strip and the length of the sail's base depends upon the shape of the triangular sail or not.
The length of the strip and the length of the sail's base depends upon the shape of the triangular sail.
Given information :
A triangular sail is being ordered for sailboat. It is planned to sew a thin decorative strip connecting the midpoints
Explanation :
The length of the strip depends up on the coordinates of the sail as
Therefore, the length of the strip and the length of the sail's base depends upon the shape of the triangular sail.
