  1. Turn homework in. Name three points, two lines, and a Ray. Also, find a point that is coplanar with Plane W. 5-Minute Check 1

  2. Targeted TEKS G.5(B) Construct congruent segments, congruent angles, a segment bisector, an angle bisector, perpendicular lines, the perpendicular bisector of a line segment, and a line parallel to a given line through a point not on a line using a compass and straightedge. Also addresses G.5(C). Mathematical Processes G.1(E), Also addresses G.1(B) TEKS

  4. ___ XZ is the measure of XZ. Point Y is between X and Z. XZ can be found by adding XY and YZ. Find Measurements by Adding or Subtracting Find XZ. Assume that the figure is not drawn to scale. Example 1

  5. Add. Find Measurements by Adding or Subtracting Example 1

  6. D 50.4 mm C 16.8 mm B Think, Write, Pair, Share Find BD. Assume that the figure is not drawn to scale. A. 16.8 mm B. 57.4 mm C. 67.2 mm D. 84 mm Example 1

  7. Draw a figure to represent this situation. Write and Solve Equations to Find Measurements ALGEBRA Find the value of x and ST if T is between S and U, ST = 7x, SU = 45, and TU = 5x – 3. ST + TU = SU Betweenness of points 7x + 5x – 3 = 45 Substitute known values. 7x + 5x – 3 + 3 = 45 + 3 Add 3 to each side. 12x = 48 Simplify. Example 2

  8. Write and Solve Equations to Find Measurements x = 4 Simplify. Now find ST. ST = 7xGiven = 7(4) x = 4 = 28 Multiply. Answer:x = 4, ST = 28 Example 2

  9. Think, Write, Pair, Share ALGEBRA Find the value of n and WX if W is between X and Y, WX = 6n – 10, XY = 17, and WY = 3n. A.n = 3; WX = 8 B.n = 3; WX = 9 C.n = 9; WX = 27 D.n = 9; WX = 44 Example 2

  10. Concept

  11. Concept

  12. Find Distance on a Number Line Use the number line to find QR. The coordinates of Q and R are –6 and –3. QR = | –6 – (–3) | Distance Formula = | –3 | or 3 Simplify. Answer: 3 Example 3

  13. Think, Write, Pair, Share Use the number line to find AX. A. 2 B. 8 C. –2 D. –8 Example 3

  14. Summarize what you have learned in this lesson. Use one or more good sentences.
