8/14 Segments and Angle Constructions Day 2 Practice

Follow these steps for congruent segment constructions:

1) Using the SEGMENT TOOL, make a segment CD of any length 2) Using the COMPASS TOOL, create a circle with radius AB and center point C 3) Using the POINT TOOL, mark the intersection of circle C and segment CD REMEMBER: Congruent circles have the same radius. The compass tool measures and preserves the radius. Therefore, the compass tool can be used to draw congruent segments.

Follow these steps for congruent angle constructions:

Use the tools provided to construct an angle congruent to the given angle CONSTRUCTION STEPS: 1) Use the POINT TOOL to mark point F anywhere on segment AB 2) Use the COMPASS TOOL to create a circle with radius AF and center point A 3) Mark point G where circle A intersects segment AC 4) Use the COMPASS TOOL to create a circle with radius AF and center point D 5) Mark point H where circle D intersects the ray 6) Use the COMPASS TOOL to create a circle with radius FG and center point H 7) Mark point I where circle D and circle H intersect 8) Use the SEGMENT TOOL to draw segment DI
