Answer/Step-by-step explanation:
Part A:
If a figure is divided into two equal halves by a line of symmetry, each of the pair the corresponding parts will be congruent to the other part.
Thus, based on the Symmetric Figures Theorem, the two parts in the question above are congruent as a result of the line of symmetry, line SD, which makes one part the mirror image of the other.
Therefore, Noah's congruence statement is of the pentagons is incorrect.
Part B:
Based on Symmetric Figures Theorem, AXPDS is congruent to MHZDS as the line of symmetry, line SD, makes one a mirror image of the other.
Answer:
7 i think
Step-by-step explanation:
You would solve this by realizing that 60 percent is the same as 60/100.
The word "of" is a key word meaning multiply.
So, 60/100 x 20
That is going to be 12.
Answer:
First we will split trapezium on two geometric figure.
One is rectangle and the second is right triangle.
When we subtract 11-4=7cm we get one cathetus of the right triangle a=7cm also we know hypotenuse which is c=16cm.
We will use Pythagorean theorem to find the second cathetus b
b=√16∧2-7∧2= √256-49= √207 ≈ 14.39cm =DC =>
AC =√(DC)∧2+(AD)∧2= √14.39∧2+11∧2= √207+121= √328= 18.1cm
AC=18.1cm
Good luck!!
