Learning Objective

I can construct geometric shapes using appropriate tools and describe their properties related to lines and angles.

  • 1

    A compass is a tool used to draw perfect circles or arcs with a constant radius.

  • 2

    To construct a congruent angle, first draw an arc that intersects both rays of the original angle, keeping the compass radius constant when drawing a similar arc on the new angle.

  • 3

    If all three sides of two triangles are congruent, then the corresponding angles must also be congruent.
