Isometry means lengths are preserved, and hence shapes must remain congruent.
Any dilation, stretching, etc are therefore excluded.
The transformations on the list that are examples of isometry are therefore:
rotation
translation
reflection
If p||q then, m∠1=m∠3
9x = 117
x = 117/9
x = 13
15^2 + 20^2
= 225 + 400
= 625
square root of 625 = 25
answer:<span>length of the Hypotenuse is</span> 25
Answer:
Square root of {(-2-8)^2+ (-5-1)^2}
Square root of {(-10)^2 + (-6)^2}
Square root of 100 +36
Square root of 136 = 11.66
Distance is 11.66
