Unit 1, lesson 6
2. the point (-4,1) is rotated 180 degrees counterclockwise using center (-3,0). what
are the coordinates of the image?
a. (-5,-2)
b. (-4,-1)
c. (-2, -1)
d. (4,-1)
3. describe a sequence of transformations for which triangle b is the image of triangle a.

When a point is rotated 180°, it actually get reflected towards the cemter of rotation. This works for all x=360k°+180° rotation angles

Step-by-step explanation:

(a, b) reflected 180° towards (c, d) and became (x, y). then,

(x, y) = (2c-a,2d-b)

=> (2(-3)-(-4), 2(0)-1) = (-2,-1)

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
