A dilation followed by a reflection

A translation of (x+5, y−2)

A translation followed by a reflection

Answer 1

If quadrilateral ABCD is congruent to quadrilateral EFGH, then what corresponding side is congruent to side HE?

Side AB

Side BC

Side CD

Side DA

Answer 2

Some steps to construct an angle MNT congruent to angle PQR are listed below. Step 3 is not listed:

Step 1: Use a compass to draw an arc from point Q which intersects the side PQ at point A and the side QR at point B.
Step 2: Draw a segment NT and use the same width of the compass to draw an arc from point N which intersects the segment NT at a point X.
Step 3:
Step 4: Join points N and Y using a straightedge.

Which statement describes step 3 correctly?

Answer 3

Maintaining the same width of the compass as BQ, draw an arc from point X such that it intersects the arc drawn from N in a point Y.

Use the same width of the compass as the width of NX, and draw an arc from point X such that it intersects the arc drawn from N in a point Y.

Use the same width of the compass as AQ, and draw an arc from point X which intersects the arc drawn from N in a point Y.

Maintaining the same width of the compass as AB, draw an arc from point X such that it intersects the arc drawn from N in a point Y.

@dan81someone anyone

Answer 7

@dan815

Answer 8

thease are 4 different questions

Answer 9

@aum can u help me

Answer 10

If you post many questions in one post many people will go elsewhere. try one question at a time.

Answer 11

oh okay sorry will u still help me..im stuck on these 4 questions?

Answer 12

I will do the second one.
If quadrilateral ABCD is congruent to quadrilateral EFGH, then what corresponding side is congruent to side HE?
ABCD is congruent to quadrilateral EFGH
The ordering of the letters A,B,C,D and E,F,G,H in congruency is important. They denote corresponding vertices:
A corresponds to E;
B corresponds to F;
C corresponds to G;
D corresponds to H.

Therefore HE is congruent to ??

Answer 13

side DA

Answer 14

Yes!

Answer 15

Okay thank you!
