Question

Sayed is constructing a triangle DEF congruent to triangle ABC. First, he drew a line segment congruent to BC and labeled it EF. Next, he adjusted the width of the compass to half of the length of side AB and drew an arc above segment EF from point E.

Which statement about the arc he drew is true?

It is incorrect because the width of the compass was not adjusted to the corresponding side AB.

It is correct because side DE is the corresponding side for segment AB.

It is correct because the use of compass preserves the congruency of corresponding angles.

Answer 1

should have been used to draw a segment congruent to segment AB.

Answer 2

Im really confused...

Answer 3

It is incorrect because the width of the compass was not adjusted to the corresponding side AB.

Answer 4

Read the steps Stan wrote to construct triangle PTS congruent to triangle DJK.


Step 1. Mark a point P. With the length of DK as the width of the compass, draw an arc from P. Mark a point on the arc as S.
Step 2. Use the ruler to measure side DJ and draw a segment with the same length from point P.
Step 3. With the length of KJ as the width of the compass draw an arc to intersect the segment drawn from point P.
Step 4. Mark the intersection of the segment and arc as T.


Which statement about the steps Stan wrote for the construction of the triangle DEF is true?
Steps 1 and 2 are incorrect because a ruler was not used in step 1 and a compass was not used in step 2.

It is incomplete because one step of drawing a segment before marking point P and S was not included.

Steps 2, 3, and 4 are incorrect because a compass was not used in Step 2 to preserve length and angle congruency.

All the steps are correct because the corresponding sides have congruent lengths.

For this one i marked B can you tell me if i got that one right or wrong ?

Answer 5

I think its b)

Answer 6

Ok will do .. Will you mind helping me check the rest of my work won't take long .. promise.

Answer 7

Look at triangle XYZ.



Which statement is correct about the sum of the lengths of two sides of the triangle?

It is half of the length of the third side.

It is one-fourth of the length of the third side.

It is greater than the length of the third side.

It is equal to the length of the third side.

Answer 8

I marked A

Answer 9

The first one is:
It is incorrect because the width of the compass was not adjusted to the corresponding side AB.
The Second is
It is greater than the length of the third side.
Srry for taking so long to answer! I was occupied at the time! :)
