In this activity, you will use the GeoGebra geometry tool to explore the relationships among the sides and angles of congruent triangles. If you need help, follow these instructions for using GeoGebra. Part A
Question
Perform the following series of rigid transformations on ∆ABC:

Translate ∆ABC by moving it 5 units to the right and 2 units up.
Draw the line y = -x, and reflect ∆A'B'C' across the line.
Rotate ∆A''B''C'' counterclockwise about the origin by 270°.

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
