How do you determine if a transformation is rigid or non rigid?

there are three basic rigid transformations. Reflections, rotations, and translations.

Step-by-step explanation: Reflections reflect the shape across a line. Rotations rotate a shape around a center point

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
