Sophie has been given two segments and the measure of an angle between them. she is trying to construct a congruent triangle. she has just finished one of the steps of the construction. which step will she do next? a) copy the angle. b) copy the first line segment. c) construct the segment between the endpoints of the two copied line segments. d) copy the second line segment with one endpoint at the same endpoint of the first line segment.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
