How is rigid motion used and how do i solve this problem, i am so l o s t

Stones 7, 8, 11, 12, 13 and 14

Step-by-step explanation:

Rigid motion describes a geometric transformation where all angles, sides, and the length/size of a shape is preserved. Meaning, a dilation is not a rigid motion.

A shape that can be mapped onto another shape is essentially the same shape on a different position on the plane. Shapes that can be mapped onto one another are congruent shapes (See below example)

The following stones are congruent :

The below stones have no corresponding shape:

Hope this assists you! Geometry can be frustrating. Have a nice day and spread the love!

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
