Unit 1 test – part 2 show all work whenever possible. pay close attention to point breakdowns for clues. add extra paper when needed.
1. a series of rigid transformations is applied to ∆abc to make it ∆a'b'c'. a) identify the coordinates of b'. (1 point)
b) identify the transformations used. (1 point)
c) write the order of the transformations. (1 point)
d) sketch ∆a'b'c' to verify it was a rigid transformation. it can be placed on the image above. (1 point) e) show work verifying the transformations of both point a and point c. (2 points) 2. in segment rt, the midpoint is s. if segments rt=6x-11 and rs=2x+29, what is the measure of segment rt? (2 points for a picture – clearly labeled midpoint using definition, clearly labeled segments) (3 points for an equation – equation set up, correct algebra process, measure of rt) 3. ∠abd and ∠dbc are adjacent complementary angles. if m∠abd=(3x+11)° and m∠dbc=(7x+19)°, identify the measure of ∠dbc. (2 points for a picture – clearly labeled showing both definitions of complementary and adjacent) (3 points for an equation – equation set up, correct algebra process, measure of ∠dbc)
