In an equilateral triangle, what is the word to describe that all angles are also congruent to each other?
What is equiangular.
300
These are the three types of rigid motion
What are translation, reflection, and rotation.
300
(x,y) ---> (-x,-y) - What kind of transformation does this explain?
What is a 180 degree rotation.
