  • Using similar triangles

    Students will use similar triangles and given information to calculate distances on maps and heights and lengths.

    Similar triangles

    Students will try to proof if triangles are similar using the AA~, SAS~, or SSS~. Proportions will be used.

    Congruent triangles

    Ways that triangles can be congruent:
    SSS-side-side-side
    SAS-side-angle-side
    ASA-angle-side-angle
    AAS-angle-angle-side
    HL-hypotenuse-leg

    Slope

    Students solved equations for y to put it in the slope-y-intercept form. They graphed these equations. They also determined slope from 2 given points.

    Concave and convex polygons

    Students learned the difference between concave and convex polygons.

    Parallel and perpendicular lines

    Students used slope to determine parallel and perpendicular lines. They also learned about zero slope and undefined slope.

    Angles of polygons

    Complete finding the angles of polygons by using triangulation.
    Complete the chart using this method.finding polygons angles

    birthday chair and birthday bucket

    I finally got these 2 rewards going today. If it’s your birthday (or the day we are celebrating it), you can sit in the birthday chair and get a prize from the birthday bucket. Everyone in that class will get a piece of candy!!

    review

    Use your knowledge of angles pairs for today’s handouts. Use the help sheet.
