Frequently Asked Questions

  • What topics will I learn about in Geometry?

    Geometry at HSLDA Online Academy emphasizes two- and three-dimensional reasoning skills, coordinate and transformational geometry, and the use of geometric models to solve problems. Students will use a variety of applications and some general problem-solving techniques, including algebraic skills, to explore geometric relationships. We will look for the logic and order within this world that God created, and discover properties and theorems and rules for relationships within a distinctly Christian worldview. Students will inductively develop conjectures about properties and relationships and then verify them deductively.

    Geometry can be considered to be the visual study of shapes, sizes, patterns, and positions. In this course, students will explore spatial sense and geometric reasoning while developing problem solving skills in real life.

    By the end of the course, students should be able to:

    • Solve practical problems involving angles
    • Use angle relationships to determine if two lines are parallel
    • Perform a variety of geometric constructions
    • Construct and judge the validity of a logical argument
    • Investigate, identify, and prove congruence and similarity
    • Apply the Triangle Inequality properties to solve practical problems
    • Solve practical problems involving right triangles
    • Investigate/identify/prove/use properties of quadrilaterals
    • Use polygon interior and exterior angle measures to solve problems
    • Investigate and solve practical problems involving circles
    • Use formulas for surface area and volume to solve problems
    • Make a model of a 3-d figure from a 2-d drawing and vice versa
    • Use proportional reasoning/determine effect of change to one dimension
    • Solve problems involving symmetry and transformations
  • How much homework is in Geometry?

    We estimate that the course workload will take 5-7 hours per week.

    During a typical week in this course, students will complete the following coursework:

    • 60-90 minutes of live class instruction
    • 1-2 lecture videos
    • IXL practice problems (no set number to complete)
    • 1 quiz
    • Discussion forum

    Throughout the year, students will also complete the following tasks:

    • Unit test every 2-3 weeks
    • Midterm exam and final exam
  • What books will I use in Geometry?

    The official booklist for Geometry is now available. In the official booklist, you will find information about the editions, book descriptions, and ISBN numbers.

    You can order course materials for competitive prices through the bookstore. Use the Textbook Finder to locate the required resources for your courses. Please note that while most books are available through, some titles are not carried and will need to be purchased elsewhere.

  • Am I ready to take Geometry?

    Students entering Geometry should have completed an Algebra 1 course. Students should also have a concrete knowledge of arithmetic operations and applying these operations to the real number system including integers and rational numbers. Students should also have a firm foundation regarding absolute value, square rooting, taking squares of numbers, place value, properties, and solving linear and quadratic equations.

    Please visit our Academic Readiness page for more information.

  • What is a Live Online Class Session in Geometry?

    In every HSLDA Academy course, students meet weekly with their instructor and classmates in an online classroom for additional teaching, discussion, Q&A, or group activities. The class sessions are interactive and are conducted using a web meeting software with video, audio, chat, and application sharing capabilities.

    Scheduled, real-time sessions in the online classroom are not the only form of instruction available in a HSLDA Online Academy course, but are offered in addition to lectures or other instructional materials that students are able to access online at their convenience.

    When they register, students will need to select a particular class section and live class meeting time. Additional class sections may be added to the schedule at a later point in the course registration period. Registered students will be notified of any changes to the live session schedule.

  • What if I have a schedule conflict with the listed Geometry class time?

    All live class sessions are recorded for later viewing. While it is recommended that students attend each live class session, students can make arrangements to watch the recordings and receive full participation credit.

    Students should contact their instructor at the start of their course to inform the instructor of any foreseen schedule conflicts.
