Make-that-Move Transformations: rotation, translation, and reflection. The apostrophe (')
means PRIME. For example A' is read A prime, B' is read B prime.
What transformation is 1A, 1B, 2A and 2B? You will get extra credit if
you tell me how you moved the original figure ABC to the new image A'B'C'.
I gave you an example for 1A and partly for 2A.
1A. Translation - A to A': 6 units to the right, B to B': 6 units the the
right, C to C': 6 units to the right)
1B.
2 down B to B': 7 units

∠cbe and ∠deb are same-side interior angles.

i took the test

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
