Grade 10 Symmetry and Transformations CCSS: HSG-CO.B.8
You are given two triangles, ABC and GHF, plotted on a set of axes. You know that you can map ¯AB onto ¯GH by a reflection over the x-axis and a rotation of 160° clockwise about the origin. You also know that ∠A≅∠G and ∠B≅∠H. Which of the following statements are true? There may be more than one correct answer.
- ΔABC≅ΔGHF
- ¯BC can be mapped onto ¯HF by a reflection over the x-axis and a rotation of 160° clockwise about the origin.
- ¯AC can be mapped onto ¯GF by a reflection over the x-axis and a rotation of 160° clockwise about the origin.
- m∠C=m∠F+160°
