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
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
___ 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

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
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
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
