Question

Help with geometry?

Answer 1

What do you need help with?

Answer 2

Just a few simple questions! I think I know the answers, but I'm really struggling :c

Answer 3

@Melody323

Answer 4

Depends what kind of geometry, translations, reflections, rotations?

Answer 5

Ok what are they?

Answer 6

it's based on determining posulates :)

Answer 7

like, they give visuals and information but I'm more caught in a mind bump because I'm torn between two answers, you know?

Answer 8

I will medal and fan - I just would really like to know :)

Answer 9

A statement, also known as an axiom, which is taken to be true without proof. This is a postulate so this should not be too hard. Questions and answers?

Answer 10

The figure below shows a quadrilateral ABCD. Sides AB and DC are congruent and parallel:

A quadrilateral ABCD is shown with the opposite sides AB and DC shown parallel and equal


A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram:

Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle BDC, are congruent. Side AB is equal to side DC and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by _______________. By CPCTC, angles DBC and ADB are congruent and sides AD and BC are congruent. Angle DBC and angle ADB form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel.

Which phrase best completes the student's proof?

AAS Postulate
HL Postulate
SAS Postulate
SSS Postulate

Answer 11

Proofs is what you meant, not postulates :).

Answer 12

Here is the figure :)

Answer 13

oh, whoops! yes proof :') sorry, terminology mix up

Answer 14

Side AB is parallel to side DC
. so the alternate interior angles, angle ABD and angle BDC are congruent.
. Side AB is equal to side DC
. and DB is the side common to triangles ABD and BCD.
Therefore what?

Answer 15

I am leaning towards SAS posulate

Answer 16

Correct.

Answer 17

It's congruent, yes?

Answer 18

Yes.

Answer 19

okay, thank you so much! would you mind helping me out with one more?

Answer 20

Sure. Lets see it.

Answer 21

Maria drew two parallel lines KL and MN intersected by a transversal PQ, as shown below:

Two parallel lines KL and MN with PQ as a transversal intersecting KL at point R and MN at point S. Angle KRS is shown congruent to angle MSQ.

Which theorem could Maria use to show the measure of angle KRQ is equal to the measure of angle PSN?

Alternate Exterior Angles Theorem
Alternate Interior Angles Theorem
Same-Side Interior Angles Theorem
Vertical Angles Theorem

Answer 22

here is the lines :)

Answer 23

Hold on, I am thinking about this....Might take me 5-10 minutes, If i cannot figure it out then, I will have you tag someone else okay? ^-^

Answer 24

No problem! thank you so much :)

Answer 25

Do you know what each of those stand for?

Answer 26

Notice the position of the angles.

Answer 27

The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.

Answer 28

@mathstudent55 Hiya!
