The coordinates of the vertices of TriangleRST are R(-3, -1) S(-1, -1), and T(-4, -5) The coordinates of the vertices of TriangleR'S'T' are R'(1, -2), S'(1, 0), and T'(5. -3) What is the sequence of transformations that maps TriangleRST to TriangleR'S'T'?

A sequence of transformations that maps RST to R'S'T' is a [ rotation of 90° counterclockwise about the origin ] followed by a [ translation].

The dashed triangle is the image of the solid triangle. The center of the dilation is (6, 6). What is the scale factor used to create the dilation.

-0.2

Select Translation, Reflection, or Rotation to identify the single transformation that transforms TriangleRST to TriangleR'S'T'

1. Two triangles looking the same and same direction too > translation 2. Two triangles facing inward toward each other (looking kinda like the BTS door logo but triangles going in if you catch my drift) > reflection 3. Two triangles (imagine door wedges but facing each other and slightly passing each other or side by side and you get ..) > rotation 4. Two triangles the same shape but one is slightly further and slightly below > translation

The rule (x, y) --> (x-1, y+3) represents a translation 1 unit [ _____ ] and 3 units [ ___ ].

1. [ left ] 2. [ up ]

Trapezoid W'X'Y'Z' is the image of trapezoid WXYZ under a dilation through point c. (Numbers are 18mm and 15mm)

What is the correct classification for each given angle?

<AFB --> [ acute ] <DFB --> [ obtuse ] <CFD --> [ right ]

(X, y) --> (x-5, y+6)

Gray Triangle: [-7, 2] [-4, -1] [-6, 5] Answer: [-7, -1] [-6, 2] [0,0]

Graph the image of the given triangle rotated 90° counterclockwise about the origin.

Gray Triangle; 1. [2,2] 2. [ 7, 1 ] 3. [-4, 8] Answer; [-2,2] go up then mark [1, 7] then move to the right and mark [4, 8] It should be slightly wider and rotated from the gray.

What is the name of the line of reflection for the pair of figures? (Two hearts except there is two arrows in the middle intersecting labeled 'm' and 'n' while the other heart has an arrow splitting it with the label 'p'

Line M

Solve for x. X° 108° 113° 132° 75° 160°

x = 132°
