The Cartesian Coordinate System and the Distance Formula
Hi,
I was wondering if my answers look correct
1 C 1. Draw a Cartesian Coordinate system for yourself, and then determine whether these sets of points form triangles
Set 1: (0,0), (1,1), (0,1) Set 2: (1, 0), (1,1), (3,2) Set 3: (0,0), (5,0), (3,5)
A set 1 line segment, set 2 Triangle, set 3 line segment Bset 1 Triangle, set 2 Triangle, set 3 line segment Cset 1 Triangle, set 2 line segment, set 3 Triangle Dset 1 line segment, set 2 line segment, set 3 line segment E set 1 Triangle, set 2 line segment, set 3 line segment F set 1 line segment, set 2 Triangle, set 3 Triangle
2B 2. I have placed a square that is 2 units long on each side so that its sides are parallel to the x or yaxis, but it's center is right on the origin. What are the coordinates of the corners?
A (1,1), (1,1), (1,1), (1,1) B(1,1), (1,1), (1,1), (1,1) C(1,1), (1,1), (1,1), (1,1) D(1,1), (1,1), (1,1), (1,1) E (1,1), (1,1), (1,1), (1,1) F (1,1), (1,1), (1,1), (1,1)
3 E 3. What shape do these four points make? (Draw from one to the next in the order given, and then draw from the last back to the first).
(0,1), (1,1), (0,3), (1,1)
A A pentagon BAn octagon C A triangle DA square E A rhombus F A cube
4. D 4. Now do the same with this list, and describe the shape.
(0,1), (0,3), (1,1), (1,1)
A A square BTwo acute angles that meet at the acute angles CA triangle DTwo right triangles that meet at the right angles E A rhombus F Two obtuse triangles that meet at the hypotenuse
What shape is created by the following points? (Do not connect these in order, just connect around the outside of the shape.)
5. C 5. (1, 0), (2, 0), (2, 4), and (1, 4)
A a rectangle Ba square Ca parallelogram Da rhombus E a triangle F a line segment
6.F 6. (2, 1), (6, 1), (7, 6), and (3, 6)
A a line segment Ba trapezoid Ca square Da rhombus E a triangle F a parallelogram
7. B 7. (1, 1), (1, 3), (9, 1), and (5, 3)
A a line segment Ba trapezoid Ca square Da rhombus E a triangle F a parallelogram
8.F 8. (8, 5), (2, 3), (5, 3), and (5, 5)
A a parallelogram Ba trapezoid Ca square Da rhombus E a triangle F a rectangle
9.A 9. (5, 1), (2, 1), (2, 4), and (13, 4)
A a trapezoid B a line segment C a square D a rhombus E a triangle F a parallelogram
10.D 10. (7, 9), (3, 13), and (11, 13)
A a rhombus B a trapezoid C a square D a right triangle E a circle F a line segment

Re: The Cartesian Coordinate System and the Distance Formula
Hi;
1C is correct. 2 B is correct.
3 E is correct.
4 I get E. Those are the same points as in 3.
In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
