In line segment AB there are two points. Point A and Point C. Point A an end point's coordinates are (8,3) while Point C a midpoint's coordinates are (5,4). Find the coordinates for point B an endpoint.

The coordinates for Point B are (2,5).

Why can't two triangles be congruent by using AAA Triangle Similarity?

Because the side lengths can be changed while the angles are still the same.

Name the steps required for constructing a perpendicular bisector on a line segment.

1.Place the compass at one end of line segment.

2.Adjust the compass to slightly longer than half the line segment length

3.Draw arcs above and below the line.

4.Keeping the same compass width, draw arcs from other end of line.

5.Place ruler where the arcs cross, and draw the line segment.

In a triangle ABC the coordinates are (3,8), (4,5) and (2,9). Perform a 90 degree clockwise rotation and reflect it over the x-axis. Label the coordinates.

(8,3), (5,4) and (9,2).

Richard asked his friends about how many glasses of water they drank. He gathered all the data together. This was his data (2,4,5,5,5,6,6,8,9,11). Using the data find the median, IQR and the outliers. 

The median is 5.5, the IQR is 4.5 while there are no outliers.

In a scatter plot what are 3 types of correlation? Explain what the correlations mean.

Positive Correlation: As one variable increases the other increases. 

No Correlation: As one variable increases the other neither increases nor decreases

Negative Correlation: As one variable increases the other decreases.
