  • Lesson 3-2 Properties of Parallel Lines

    Use the diagram below. Find the measure of each angle. Justify your answer.

    1. angle 1
    2. angle 2
    3. angle 3
    4. angle 4

      A transversal intersects two parallel lines, forming two X-shaped intersections. The top left intersection has angle 1 at the right, angle 2 on top, and angle 4 on the left. The bottom right intersection has angle 110 degrees on top and angle 3 on the left.

  • Lesson 4-1 Naming Congruent Parts

    white up pointing triangle p eh c approximately equal to white up pointing triangle d h l .  Complete each congruence statement.

    1. p c bar , approximately equal to , modified under bar with
    2. angle , h approximately equal to . modified under bar with
    3. angle p c eh approximately equal to , modified under bar with
    4. white up pointing triangle h d l approximately equal to , modified under bar with
  • Lessons 4-2 and 4-3 Triangle Congruence

    Write a congruence statement for each pair of triangles. Explain why the triangles are congruent.

    1. Triangles PKN and MLN share vertex N, with sides KN and LN congruent and sides PN and MN congruent.
    2. Triangles ABC and EBD share vertex B, with sides AB and EB congruent and angles C and D congruent.
    3. Triangles HUG and BUG share side UG, with sides HG and BG congruent and sides HU and BU congruent.
  • Lesson 5-1 Midsegments of Triangles

    Use the diagram below for Exercises 12–13.

    1. If b c , equals 12 , comma  then b f equals , modified under bar with and d e equals . modified under bar with

      Triangle ABC has midsegments connecting D on side AC, E on side AB, and F on side BC.

    2. If e f , equals 4.7 comma  then eh d equals , modified under bar with and eh c equals . modified under bar with
