In this activity, you will use the GeoGebra geometry tool to explore the relationships between the various pairs of angles formed when a transversal cuts two parallel lines. Open parallel lines and transversals C, and complete each step below. If you need help, follow these
instructions for using GeoGebra.
Question 1
Measure and record all eight angles formed between the transversal EF and the parallel lines AB and CÓ. Place the label of each
angle so you can see it clearly. Take a screenshot of your diagram showing the measures of all the angles, and paste it in the space below.

What makes a trapezoid an isosceles trapezoid?

Awindow has the shape of a rectangle with a semi circle at the top. find the approximate area of the window using the dimensions shown. 4ft by 8ft

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
