Triangle ABC has vertices A (-3, 1), B (0, 3), and C (3, 0) and is dilated by a factor of 1/2 using point (-2, 1) as the point of dilation. The dilated triangle names A’ B’ C’. What are the coordinates of the vertices of the resulting triangle?

Dilations change a shape's size by a number (better known as a factor). You multiply the factor by the numbers for each point:

correct answer:

b.(19,-2)

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
