Geometry help!!

Answer 1

1. Which correspondence accurately describes the two congruent triangles shown here? http://i.imgur.com/0DlR9Vf.gif

triangleABE = triangleBCD
triangleAEB = triangleCBD
triangleEAB = triangleDBC
triangleABE = triangleCBD

2. What is the measure of angY?

60°

180°

30°

Not enough information given

Thank you :)

Answer 2

Looking at the diagram and the number of arcs used to mark congruent angles,
the correspondence of vertices has to be:

D<->E
C<->A
B<->B

Of the options, pick the one that preserves the correspondence.
Because B must correspond to B, you can quickly eliminate some of the options.

If you post what you get, we can compare answers, okay? @Nannarzz

Answer 3

For the second question:

Because of the single slash marks on each of the three sides of the triangle, we know that the triangle is equilateral. All three sides have the same length.

If a triangle is equilateral, then it is also ___?____ which would give each angle a measure of ___?____

Answer 4

I'm awful with geometry, but based on what you said, I picked the third choice. It's the only one with that correspondence you showed. And for the second one, I picked option 1, because if every angle is 60°, it adds up to 120°. Am I heading in the right direction with these questions, or am I missing anything?

Answer 5

>> if every angle is 60°, it adds up to 120°

If every angle is 60, then the sum of the angles of the triangle is 180.

Answer 6

I meant 180 :P. I hit the wrong number

Answer 7

If this is what you selected for the first question: triangle EAB = triangle DBC ,
then it is wrong.

In triangle EAB = triangle DBC,
E<->D
A<->B
B<->C
This is wrong because B has to correspond to B.

So, try again on question 1.

Answer 8

@Nannarzz Your answer to question #1 is wrong. Read the above. ^^^

Answer 9

Okay, I see now, with my choice, B doesn't correspond with b. From the looks of the other choices, the only one that would make sense, is the last one.
A <-> C
B <-> B
E <-> D

Answer 10

@Nannarzz

Yes. triangleABE = triangleCBD
That is what I got.

Answer 11

@Directrix Thank you so much :). You explained this stuff better than my school did.

Answer 12

You are welcome.
