Question

Use ΔABC below to answer the question that follows:

Which fact is not used to prove that ABC is similar to DBE? (5 points)

The sum of angles A and B are supplementary to angle C.

Segments AC and DE are parallel.

AB is a transversal line passing AC and DE.

Angle B is congruent to itself due to the reflexive property.

Answer 2

gosh my computer is slower than a snail in mollasses during winter!

Answer 3

ac/ef=ab/ed=bc/df

Answer 4

AB/ED = BC/DF

Answer 5

If one angle of a triangle is equal to one angle of other triangle and the corresponding sides including this angle are proportional,then two triangles are similar

Answer 6

AB over ED equals BC over DF so their respective angles are equal so, ∠A ≅ ∠E and ∠C ≅ ∠F if all three angles of ΔABC and ΔEDF are equal then ΔABC is similar to ΔEDF

Answer 7

AC/EF=AB/ED = BC/DF

why did my mom get comcast!!??

Answer 10

comcast????

Answer 11

yea

Answer 12

cuz of me

Answer 13

Answer 21

*phew!*

Answer 22

okay then I am serious

Answer 23

and so sorry

Answer 24

can you help me with this one?

Given: ΔABC is a right triangle.

Prove: a2 + b2 = c2

The two-column proof with missing justifications proves the Pythagorean Theorem using similar triangles.

Statement Justification
Draw an altitude from point C to
Let = a
= b
= c
= h
= x
= y
y + x = c

a2 = cy; b2 = cx
a2 + b2 = cy + b2
a2 + b2 = cy + cx
a2 + b2 = c(y + x)
a2 + b2 = c(c)
a2 + b2 = c2

Which is not a justification for the proof? (5 points)

Addition Property of Equality

Pythagorean Theorem

Pieces of Right Triangles Similarity Theorem

Cross Product Property

Answer 25

what do you want to proof pythagoras theorem rite

Answer 26

u there

Answer 27

no i need to find the wrong justification

Answer 28

yea my computer is slow thats all

Answer 29

okay wait a min

Answer 30

u there?
