4-4: TEKS Practice

  • 1. In the graph shown, the post office is located at P and the market is located at Q. The axes show distances in miles. Find the distance in miles from the post office to the market.

    A graph of a line segment from P(5, 3) to Q(8, 7).

  • 2. Find the distance between P and Q.

    A graph of a line segment from P(5, 3) and Q(6.5, 6.6).

  • 3. Is this triangle isosceles, scalene, or equilateral? (Figure 1)

  • 4. Reasoning You are on your way back to school from a field trip to the zoo. The point P on the graph represents the location of your school. You are on the bus located at point Q. Your friend is on the bus located at point R.

    A graph of a triangle PQR. P = (3, -6), Q = (14, -6), R = (10, -2).

    A graph of line segments from P(6, 4) to Q(12, 12), and from P to R (9.5, 16).

    • a. Who is closer to the school?

    • b. Explain your reasoning.

  • 5. Think About the Process Suppose your home is located at H. The park is 3.6 miles east of your home. The library is 4.8 miles north of the park.

    A graph of right triangle HLP: H at (0, 0), L at (3.6, 4.8), P at (3.6, 0). Legs HP and PL are dashed. Hypotenuse HL is solid.

    • a. How can you use a coordinate plane to map the distance from the library to your home?

    • b. What is the distance from the library to your home?
