Question

Triangle CAT was rotated to create triangle C'A'T'. Describe the transformation using details and degrees. Imagine points C and C' were two points on a circle named O that had the origin as its center. Now imagine points A and A' were to also lie on a circle named T with the origin as its center. What type of circles would O and T create?

Answer 4

this one is trickier ^_^ What have you got so far?

Answer 5

Notice that A is 1 unit to the left of and two above C, while A' is two to the right of and 1 above.

You can describe the rotation of the triangle *about* C (keeping C still and moving things around it) by drawing a circle with C at the center and A at the edge; then you can more easily find how many degrees the triangle was "rotated through."

Then you can also use C as a judge of the translation (it's 1 up and three to the right of where it started).

Lastly if two circles are drawn with 1 inside the other with the same origin, they're called concentric ("con" meaning "with" or "join," and centric as in "center" ). Would circle O and circle T be concentric or not?

Answer 6

Thank you for the triangles ^_^ They are perfect. If this is in relation to that older question,
