From the figure, the dilation constant from ΔABC to ΔDEF is
QD/QA = 8/4 = 2
Test QB = QE:
We should have
QB = (1/2) QE
The statement is incorrect.
Test QC = CF:
We should have
QC = (1/2) QF, or QC = CF
The statement is correct.
Test DE = 2AB:
We should have
AB = (1/2)DE, or 2AB = DE.
The statement is correct.
Test AC = EF:
We should have
AC = (1/2)DF
The statement is incorrect.
We should also have
BC = (1/2)EF
Therefore, if BC = 2.25, then
EF = 2*BC = 2*2.25 = 4.5.
Answer:
QC = CF
DE = 2AB
EF = 4.50
That is true. Since the area of a triangle is 1/2bh the b and h don't change if the triangles are the same
Hi, I think it might be:
A) 10000000+700000+20000+7000+400+90+5
B) ten million, seven hundred and twenty seven thousand, four hundred and ninety five.
The sum is adding
3 times a number is 3x
And 15 is +15
3x+15
