Question

You are going to make rotations, translations, reflections, and dilations to a triangle, using its initial coordinate points for each one.

Answer 1

90 clockwise rotation: A(3,-2), B(-1,0), C(-1,-40
180 counter-clockwise rotation: A(-2,3), B(0,-1), C(-4,-1)
Translation 3,5: A(-3,0), B(-4,-5), C(-1,-5)
Reflection y axis: same as 180 rotation
Dialation of 2.1: A(4.2,6.3), B(0,-2.1), C(8.4,-4.2)
