How many degrees did you rotate your triangle? 2.5 transformation and congruence activity

Step-by-step explanation:

How do you draw

the image of a figure under a rotation?

Possible To draw the image of a figure

under a rotation of m° around point P, choose a

vertex of the figure, for example, vertex A. Draw ¯PA .

Use a protractor to draw a ray that forms an angle of

m° with _

PA . Use a ruler to mark point A' along the

ray so that PA' = PA. Repeat the process with the

other vertices of the figure. Connect the images of

the vertices (A′, B′, etc.) to draw the image of the

figure. If the figure is on a coordinate plane, use an

algebraic rule to find the image of each vertex of

the figure. Then connect the images of the vertices.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
