Question

Which theorem or postulate would be used to prove XYV WZV?

Answer 1

What parts of one triangle do you have that are congruent to corresponding parts of the other triangle, and in what order?

Answer 2

By parts I mean sides and angles.

Answer 3

it doesn't say

Answer 4

Look in the figure.

Answer 5

Is side YV congruent to a side of the other triangle?

Answer 6

i don't get you . sorry

Answer 7

Is side XV congruent to a side of the other triangle?
Is angle YVX congruent to an angle of the other triangle?

Answer 8

yea

Answer 9

Ok, I'll start from the beginning and will go slowly.

Look at triangle VXY.
It has 3 sides.
They are called side YX, side XV, and side YV.
So far ok?

Answer 10

yea

Answer 11

Now look closely at the right triangle.
It also has 3 sides.
They are side VW, side WZ and side VZ.
Ok?

Answer 12

ok

Answer 13

Now, do you notice that side YV and side VZ each has a little mark on it?

Answer 14

@hedgehog Are you still there?

Answer 15

yea sorry

Answer 16

i gotta go now . bye my friend

Answer 17

bye

Answer 18

The single small marks on thoses sides mean those sides are congruent.
The double small marks on sides XV and VW mean those two sides are congruent.
The angle marks on angle YVX and angle ZVW mean the angles are congruent.
You have a Side, and Angle, and a Side of one triangle congruent in that order to corresponding parts of another triangle. That's what allows you to conclude the triangles are congruent.
