Follow the steps below to copy angle [i]BAC[/i]:[br][list=1][br][*]In the space below angle [i]BAC[/i], draw ray [i]RY[/i].[br][*]Using [i]B[/i] as center, use the circle tool to draw an circle of any radius that intersects both ray [i]BA[/i] and ray [i]BC[/i]. Construct points [i]D[/i] and [i]E[/i] where the circle intersects those rays.[br][*]Use the segment tool to construct any radius of the circle you just constructed in Step 2.[br][*]Use the Compass tool and select the segment you constructed in Step 3 and then point [i]R[/i] to construct a circle centered at [i]R[/i] with the same radius as the circle you constructed in Step 2. Construct point [i]S[/i] where this circle intersects ray [i]RY[/i].[br][*]Construct segment [i]DE[/i].[br][*]Use the compass tool and select segment [i]DE[/i] and then point [i]S[/i] to construct a circle that intersects the circle centered at [i]R[/i] that you constructed in Step 4 at point [i]Q[/i].[br][*]Draw ray [i]RQ[/i].[br][/list][br]Drag point A around and note your observations. Angle [i]QRS[/i] should remain congruent to angle [i]ABC[/i].
