a.
To determine the geometric figures.
a.
Answer to Problem 12CYU
Points
Explanation of Solution
Given information:
Ursa Minor
Calculation:
Concluding from the given figure, the Ursa Minor represents points with no specific shape or size.
b.
To determine the collinear stars
b.
Answer to Problem 12CYU
Star 1, star 2 and star 3 are not collinear.
Explanation of Solution
Given information:
Ursa Minor
Formula used:
Collinear point definition
Calculation:
Collinear points lie on the same line. Concluding from the shape of Ursa Minor, star1, star2 and star3 are not collinear.
c.
To determine the coplanar stars
c.
Answer to Problem 12CYU
Polaris, star 2 and star 6 are coplanar
Explanation of Solution
Given information:
Ursa Minor
Formula used:
Coplanar definition
Calculation:
Coplanar are the points which lie on the same plane. From the image, all the three stars appear on the same plane, hence Polaris, star 2 and star 6 are coplanar.
