Question 1

Look at the triangles in the diagram.

Determine which of the statements is correct.

Question 2

Look at the triangles in the diagram.

Which of the following statements is true?

Question 3

Look at the triangles in the diagram.

Which of the following statements is true?

Question 4

Are the triangles in the image congruent?

If so, according to which theorem?

Question 5

Which of the triangles are congruent?

Look at the triangles in the diagram.

Determine which of the statements is correct.

Let's consider that:

AC=EF=4

DF=AB=5

Since 5 is greater than 4 and the angle equal to 34 is opposite the larger side in both triangles, the angle ACB must be equal to the angle DEF

Therefore, the triangles are congruent according to the SAS theorem, as a result of this all angles and sides are congruent, and all answers are correct.

All of the above.

Look at the triangles in the diagram.

Which of the following statements is true?

According to the existing data:

$EF=BA=10$(Side)

$ED=AC=13$(Side)

The angles equal to 53 degrees are both opposite the greater side (which is equal to 13) in both triangles.

(Angle)

Since the sides and angles are equal among congruent triangles, it can be determined that angle DEF is equal to angle BAC

Angles BAC is equal to angle DEF.

Look at the triangles in the diagram.

Which of the following statements is true?

This question actually has two steps:

In the first step, you must define if the triangles are congruent or not,

and then identify the correct answer among the options.

Let's look at the triangles: we have two equal sides and one angle,

But this is not a common angle, therefore, it cannot be proven according to the S.A.S theorem

Remember the fourth congruence theorem - S.A.A

If the two triangles are equal to each other in terms of the lengths of the two sides and the angle opposite to the side that is the largest, then the triangles are congruent.

But the angle we have is not opposite to the larger side, but to the smaller side,

Therefore, it is not possible to prove that the triangles are congruent and no theorem can be established.

It is not possible to calculate.

Are the triangles in the image congruent?

If so, according to which theorem?

Although the lengths of the sides are equal in both triangles, we observe that in the right triangle the angle is adjacent to the side whose length is 7, while in the triangle on the left side the angle is adjacent to the side whose length is 5.

Since it's not the same angle, the angles between the triangles do not match and therefore the triangles are not congruent.

No.

Which of the triangles are congruent?

Let's observe the angle in each of the triangles and note that each time it is opposite to the length of a different side.

Therefore, none of the triangles are congruent since it is impossible to know from the data.

It is not possible to know based on the data.

Question 1

What data must be added so that the triangles are congruent?

Question 2

What data must be added so that the triangles are congruent?

Question 3

Are the triangles in the drawing congruent?

Question 4

Look at the triangles in the diagram.

Which of the statements is true?

Question 5

ABCD is a kite.

E and F are extensions of diagonal BD.

semicircles are drawn with BE and FD as their bases.

BE = 2X

AF = AE

Calculate the sum of the areas marked in blue.

What data must be added so that the triangles are congruent?

Let's consider that:

DF = AC = 8

DE = AB = 5

8 is greater than 5, therefore the angle DEF is opposite the larger side and is equal to 65 degrees.

That is, the figure we are missing is the angle of the second triangle.

We will examine which angle is opposite the large side AC.

ABC is the angle opposite the larger side AC so it must be equal to 65 degrees.

Angle ABC equals 65.

What data must be added so that the triangles are congruent?

It is not possible to add data for the triangles to be congruent since the corresponding angles are not equal to each other and therefore the triangles could not be congruent to each other.

Data cannot be added for the triangles to be congruent.

Are the triangles in the drawing congruent?

In order for triangles to be congruent, one must demonstrate that the S.A.S theorem is satisfied

We have a common side whose length in both triangles is equal to 3.

Now let's examine the lengths of the other sides:

$2X+4=X+2$

We proceed with the sections accordingly:$2-4=2X-X$

$-2=X$

We place this value in the right triangle we should find the length of the side:$-2+2=0$

However since it is not possible for the length of a side to be equal to 0, the triangles are not congruent.

No
