Question

Geometry questions???? Will fan and give medal for help???? Attached below

Answer 1

you want all of them done

Answer 2

Do you have any ideas for any of them?
Just asking what you have done/thought of already

Answer 3

I believe the first one is D and the second one is A

Answer 4

I'm not 100% sure on either of them though. @SolomonZelman

Answer 5

1 D is correct

Answer 6

and #5 i think it's 70.

Answer 7

for number 2, lets look at that now.

Answer 8

you are given Side and Angle in the question, and in addition to this, you have a side AD.

Answer 9

so the angles in number 2 are congruent by what postulate?

Answer 10

SAS

Answer 11

yes

Answer 12

I think number 3 is SSS @SolomonZelman

Answer 13

yes looks like it

Answer 14

how about 4?

Answer 15

SAS @SolomonZelman

Answer 16

angle? where do you see angles here?

Answer 17

Oh wait

Answer 18

I think it's SSS

Answer 19

I don't think 2 sides are given:

you can see that PT forms the hypotenuses of the 2 triangles, and you know that the rest of the legs are respectively equivalent

Answer 20

HL postulate ? It's not ASA since there's no angles

Answer 21

yes D

Answer 22

for 5, can you find the answer?

Answer 23

and 5 I think it's 70

Answer 24

70 would be Angles A & B together, no?

Answer 25

Oh, yeah it would be, so A=35

Answer 26

yes.

Answer 27

because if the sides that \(\large\color{slate}{ \angle A }\) and \(\large\color{slate}{ \angle B }\) are equal (and they are)

then the angles themselves are also equal.

Answer 28

And \(\large\color{slate}{ \angle C=110 }\), then each \(\large\color{slate}{ \angle A }\) and \(\large\color{slate}{ \angle B }\) would be 1/2 of that, which is 35.

Answer 29

now about number 6?

Answer 30

I think #6 is B but I'm really unsure...

Answer 31

Since it is isosceles \(\large\color{slate}{ \triangle }\), therefore (knowing that the right and left side are equivalent)
then the two bottom angles are also equivalent

Answer 32

so the other angle on the left would be \(\large\color{slate}{ 75^\circ }\) as well as the angle on the right.

Answer 33

Now, can you find the top angle?

Answer 34

30

Answer 35

yes

Answer 36

can you do number 7?

Answer 37

I will give a hint:

Answer 38

You have:
AC=DC
BC=AD
and also the two triangles have another side in common that they share.

Answer 39

So what would your answer be?

Answer 40

SAS

Answer 41

any angles? I don't see any angle congruences given

Answer 42

you have sides:
AC=DC
BC=AD
side AC is shared by 2 triangles

Answer 43

SSS

Answer 44

yes

Answer 45

and for 8 I think it's A

Answer 46

what does CPCTC stand for?

Answer 47

I don't know, actually. @SolomonZelman

Answer 48

I was asking because I didn't know

Answer 49

hm, I didn't read about it in my lessons

Answer 50

`Corresponding Parts of Congruent Triangles are Congruent`

Answer 51

which would it be, do you know?

Answer 52

I think it's A

Answer 53

try to think of having two triangles being congruent respectively (looking at the shape) and look at the options.

Answer 54

firstly, if in options, you see triangles that go into each other, exclude that.

Answer 55

which options can you exclude?

Answer 56

C & D

Answer 57

I think before I meant to say B

Answer 58

so which options do you exclude?

Answer 59

C & D

Answer 60

yes correct

Answer 61

I think it is A, because the corresponding parts are in order there, unlike B
