  • TEKS
    • G.5(A) – investigate patterns to make conjectures about geometric relationships, including angles formed by parallel lines cut by a transversal, criteria required for triangle congruence, special segments of triangles, diagonals of quadrilaterals, interior and exterior angles of polygons, and special segments and angles of circles choosing from a variety of tools
    • 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 a straightedge
    • G.6(E) – prove a quadrilateral is a parallelogram, rectangle, square, or rhombus using opposite sides, opposite angles, or diagonals and apply these relationships to solve problems

  1. Hello! I am loving your curriculum this year! Quick question, why are some of your practices asking questions that involve right triangle trig? We have not covered it yet.

    1. Hey Stephen! Thank you for the kind words! I’m glad the resources have been useful. To answer your question, I’ve reordered the curriculum this year to match a change in the sequence of topics in our district. Unfortunately, I haven’t been able to update the practice assignments to fit this change yet. So, you’ll have to rework some things as you go through.

      Thank you for checking in! Let me know if you find other areas that need improvement as well.
