Answer:
13
Step-by-step explanation:
n+(n+2)+(n+4)=42
3n+6=42
3n=42-6=36
3n=36
n=13
13+14+15=42
Answer:
Step-by-step explanation:
It's not rigid because dilations (scale factor not equal to 1) change the length of the segments, or the distances between the points. You'll get a similar figure but it won't be congruent. For example, if the scale factor is 3, then the distances will be three times as large; or the lengths will be 3 times as long.
To be "rigid", the lengths must be kept the same. In contrast, a reflection is rigid because the distances are kept the same. The only thing changing is the orientation (clockwise to counter-clockwise, or vice versa).
