  1. Step 1: Draw a ray with endpoint T. Step 2: Open the compass to the length of KM. Step 3: With the same compass setting, put the compass point on point T. Draw an arc that intersects the ray. Label the point of intersection W. TWKM Basic Constructions LESSON 1-7 Additional Examples Construct TW congruent to KM. Quick Check

  2. Step 1: Draw a ray with endpoint Y. Step 2: With the compass point on point G, draw an arc that intersects both sides of G. Label the points of intersection E and F. 75° Step 3: With the same compass setting, put the compass point on point Y. Draw an arc that intersects the ray. Label the point of intersection Z. Basic Constructions LESSON 1-7 Additional Examples Construct Y so that YG.

  3. Step 4: Open the compass to the length EF. Keeping the same compass setting, put the compass point on Z. Draw an arc that intersects the arc you drew in Step 3. Label the point of intersection X. Step 5: Draw YX to complete Y. Y G Basic Constructions LESSON 1-7 Additional Examples (continued) Quick Check

  4. Start with AB. Step 2: With the same compass setting, put the compass point on point B and draw a short arc. Step 1: Put the compass point on point A and draw a short arc. Make sure that the opening is less than AB. 1 2 Basic Constructions LESSON 1-7 Additional Examples Quick Check 1 2 Use a compass opening less than AB. Explain why the construction of the perpendicular bisector of AB shown in the text is not possible. Without two points of intersection, no line can be drawn, so the perpendicular bisector cannot be drawn.

  5. Step 1: Put the compass point on vertex M. Draw an arc that intersects both sides of M. Label the points of intersection B and C. Step 2: Put the compass point on point B. Draw an arc in the interior of M. Basic Constructions LESSON 1-7 Additional Examples Construct MX, the bisector of M.

  6. Step 3: Put the compass point on point C. Using the same compass setting, draw an arc in the interior of M. Make sure that the arcs intersect. Label the point where the two arcs intersect X. Step 4: Draw MX. MX is the angle bisector of M. Basic Constructions LESSON 1-7 Additional Examples (continued) Quick Check
