Question

ABC is an isosceles right triangle in which AB has a slope of -1 and angle ABC = 90 degrees. Triangle ABC is dilated by a scale factor of 1.8 with the origin as the center of dilation, resulting in the image A'B'C'. What is the slope of B'C'?

Answer 1

@dumbcow

Answer 2

dilating only changes the length of the sides not the shape of the triangle

you still have a isosceles right triangle with slope of -1 for A'B'

so slope of B'C' is same as slope of original BC which is straight line or 0

Answer 3

Thank you @dumbcow I still don't understand it very well although you explained it but thank you for your time and knowledge :)

Answer 4

yw maybe a picture will help



sorry i misread the problem
in this case BC is perpendicular to AB

perpendicular slopes must always multiply to -1

---> (-1)*x = -1
----> x = 1

slope of BC = 1 thus B'C' is also 1
