Solution:

#### 1. Construct a line segment congruent to the one.
- Steps:
1. Use the straightedge to draw a new line.
2. Place the compass on one endpoint of the given segment and adjust it to span the entire length of the segment.
3. Without changing the compass setting, place the compass on the new line at a chosen point (which will be one endpoint of the new segment).
4. Draw an arc intersecting the new line. The intersection point is the other endpoint of the new segment.
5. The new segment is now congruent to the original segment.

#### 2. Construct an angle congruent to the one shown.
- Steps:
1. Draw a ray (part of a line) where you want the new angle to be.
2. Place the compass on the vertex of the given angle and draw an arc intersecting both sides of the angle.
3. Without changing the compass setting, place the compass on the endpoint of the ray you drew and draw an arc.
4. Measure the distance between the two points where the first arc intersects the sides of the given angle using the compass.
5. Using the same compass setting, place the compass on the intersection of the second arc and the ray, and mark an arc intersecting the second arc.
6. Draw a ray from the endpoint of the original ray through the intersection of the two arcs. This forms the congruent angle.

#### 3. Construct a copy of all the angles in the quadrilateral.
- Steps:
1. For each angle in the quadrilateral, follow the steps outlined in part 2 above.
2. Repeat the process for each of the four angles in the quadrilateral.
3. Ensure that the copied angles are placed in the correct orientation relative to each other to form a quadrilateral congruent to the original.

#### 4. Construct a line segment with a measure that is twice the length of the given segment.
- Steps:
1. Draw a new line.
2. Use the compass to measure the length of the given segment.
3. Place the compass on a chosen point on the new line and mark an arc to create the first segment.
4. Without changing the compass setting, place the compass on the endpoint of the first segment and mark another arc on the new line.
5. The total length between the starting point and the second arc is twice the length of the original segment.

#### 5. Construct a line segment with a measure that is the sum of the two segments shown.
- Steps:
1. Draw a new line.
2. Use the compass to measure the length of the first segment.
3. Place the compass on a chosen point on the new line and mark an arc to create the first segment.
4. Measure the length of the second segment using the compass.
5. Without changing the compass setting, place the compass on the endpoint of the first segment and mark another arc on the new line.
6. The total length between the starting point and the second arc is the sum of the lengths of the two original segments.

#### 6. Construct a triangle using these three segments.
- Steps:
1. Use the compass to measure the length of the first segment and draw it as the base of the triangle.
2. Place the compass on one endpoint of the base and set it to the length of the second segment. Draw an arc above the base.
3. Place the compass on the other endpoint of the base and set it to the length of the third segment. Draw another arc above the base, intersecting the first arc.
4. Mark the intersection point of the two arcs.
5. Draw lines connecting this intersection point to both endpoints of the base. The resulting figure is a triangle with sides congruent to the three given segments.
