Plot the point A(4,0) and B(0,4),Join AB to origin O.Find area of triangleAOB.
AOB is a triangle with coordinates of A and O as (4,0) and (0,0),AB=5.Find the coordinates of B.
Three vertices of a rectange are aas (3,2),(-4,2) and (4,-5).Plot these points and find the coordinates of the fourt vertices.
The Question Marks are what I need to know the answers to. The first statement answer is obviously "Given". I believe the second is "Segment Addition Postulate" for the third one down I have "Transitive Property". Fourth I have "Segment Addition Postulate". Fifth "Transitive Property". Sixth "Addition Property". Seventh and Eighth I put "Symmetric Property" I need to know if this is correct. This is the problem:

In the Diagram below AC=BD. Fill in the reasons to show that line CD=̃AB.
A________B_______________________C____D


Statements/ Reasons (the question marks represent the postulates that I need to identify)

1) AC=BD (?)
2) AC=AB+BC (?)
3) AB+BC=BD (?)
4) BD=BC+CD (?)
5) AB+BC=BC+CD (?)
6) AB=CD (?)
7) CD=AB (?)
8) CD=̃AB (?)

Line segment AB has a midpoint C
If AC=17 and AB = 5x-6, then find the value of x
B is the center of the larger circle and C is the center of the smaller circle. A is a point on the larger circle such that angles ABC form a right angled triangle, and the length of AC is 5. the bigger circle has area 9 pie. what is the perimeter of the bigger circle and the perimeter of the smaller circle?
The radius of D is 5cm. Indicate whether the point described is inside, or outside, or on D.
A. Point X: 6 cm from D. B.Point Y: 4cm from D

C. Point Z: 5cm from D
Assume you and a buddy are standing on the surface of a sphere of unknown size. You are exactly the same latitude, north of the equator, an arbitrary distance apart (x). You each travel north a known distance (y), and then remeasure your distance apart from each other (z). Given those three measurements, would you be able to calculate the circumference and hence the size of the sphere? What would the formula be?
