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).
Answer:
Step-by-step explanation:
Given
The attached figure
Solving (a): EF
Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.
So, EF will be calculated using Pythagoras theorem which states:
Take the positive square roots of both sides
Solving (b): GH
Since m is a perpendicular bisector, then GH = FG
Solving (c): EH
Since m is a perpendicular bisector, then EH = EF
Answer:
640
Step-by-step explanation:
first you have to do the 11-9 its gonna be 2 then you have to the cubic of 2 wich is 8 and after it you have to get 8 divided by 2 youre gonna get 4
after it you have to start from the left 320/4 equal to 80 than 80by 8 equal to 640
Answer:
$5184
Step-by-step explanation:
1 per square foot =$432/1
12 square =12×$432/1
$5184
Answer:
35 units
Step-by-step explanation:
because the area of a parallelogram is base times height so its 7 times 5 which is 35
