If you cut a triangle out of a piece of paper, and move that triangle around (sliding, rotating, reflecting) then that triangle will retain its original shape and size. The three movement types mentioned are rigid motions. They do not change the size or shape of the triangle. If two triangles are congruent, then a sequence of one or more rigid motions can be applied to have them line up together.
Multiply both sides by lh, V=wlh
Answer:
solution is x=3
Step-by-step explanation:

apply log property
log a- log b= log a/b

we have log on both sides
so we remove the log and make the arguments equal

solve for x, multiply whole equation by 3

now plug in 3 for x and check

solution is x=3
Answer:
Maggie is 5 years old
Step-by-step explanation:
3M-4+M=16
add 4 to both sides
4M=20
Divide both sides by 4
20/4 = 5
M/Maggie is 5
