Answer: A rigid transformation preserves both the side lengths and the angle measures of a polygon.

Step-by-step explanation:

  • Rigid transformations are the transformations which does not affect the size  and the shape of figure . The figure doesn't shrink or get enlarger.

Thus, it doesn't affect the side length or the angle measurement of the figure .

There are four rigid transformations such as :

a)reflections, b) rotations, c) translations and d) glide reflection.

Hence, the right statement from all the given statements is "it preserves both the side lengths and the angle measures of a polygon."

Answer:

B.) x=5

Step-by-step explanation:

Use the Pythagorean theorem. Since it isosceles, both values of x are the same. Split 6 in half (because perpendicular bisector).Insert values:

a^2+b^2=c^2\\3^2+4^2=x^2\\9+16=x^2\\25=x^2\\5=x

X is equal to 5.

Done.

i=prt (formular)

given:

I =?

p = $1000 or #415,640.00

r = 6%

t = 2 years

i= 415,640.00×6×2÷100

i= #49876.8

without changing currency

i= 1000×6×2÷100

i=120
