what does it mean when they ask you to use a straightedge to construct XY congruent to UV?
given: 5x+4=39
prove: 2x-3=11
what the statements and reason
Find the coordinates of the midpoint of a segment with the following midpoint A (5,2) & B(-3,-6)
At a miniature golf course, a water hazard blocks the direct shot from the tee at T (0,0) to the cup at C (-1,7). If you hit the ball so it bounces off an angled wall at B (3,4), it will do into the cup. The coordinate system is measured in feet. Draw a diagram of the situation.
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 altitude of a cone is 6 cm. A plane 3 cm from the vertex of the cone is
parallel to the base of the cone. If the volume of the smaller cone is 36
cm3, find the volume of the larger cone.
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 (?)
