7-1: TEKS Practice

  • 1. Which of the following is a pair of corresponding angles?

    Two pairs of parallel lines and a transversal crossing both pairs of lines.

    • A. ∠5 and ∠6

    • B. ∠6 and ∠7

    • C. ∠6 and ∠8

    • D. ∠1 and ∠4

  • 2. Find the measure of ∠u given that p vertical line vertical line q .

    Horizontal lines p and q intersected by a transversal

  • 3. Streets A and B run parallel to each other. The measure of ∠8 is 23°. The measure of ∠6 is 157°. Find the measure of ∠2.

    Horizontal streets A Street and B Street intersected by transversal C Street

  • 4. Find mv given that p vertical line vertical line q , mu = 75.8°, and mw = 104.2°.

    Horizontal lines p and q intersected by a transversal

  • 5.

    • a. Writing Find the alternate interior angles in the figure shown, given that m vertical line vertical line n . Which are the alternate interior angles? List all that apply.

      Vertical lines m and n intersected by a transversal

    • b. Describe a situation where you would use a transversal to cut a pair of parallel lines.

  • 6. Error Analysis On a recent math test a teacher asked for the measure of ∠w. In the figure, p vertical line vertical line q . Jacob incorrectly said that the measure was 101°.

    Horizontal lines p and q intersected by a transversal

    • a. Find the measure of ∠w.

    • b. Which error might Jacob have made?

  • 7. Rainbows When sunlight enters a drop of rain, different colors of light leave the drop at different angles, making a rainbow. In the figure shown, lines m and n represent the sun's rays. Assume that lines m and n are parallel and you are standing at point A.

    Lines m and n crossed by a transversal

    • a. For violet light at point B, m∠2 = 27° and m∠3 = 153°. What is m∠1?

    • b. Justify how you can determine m∠1.
