Using a Compass to Make Constructions
... Construct ΔMUD so that ΔMUD is congruent to ΔABC by SAS ≅. To construct a congruent triangle, we will need to use two constructions: copying a segment and copying an angle. In this example we want to construct the triangle with the SAS ≅, so we will copy a side, then an angle, and then the adjacent ...

Angle sums and more. Among other things, we will prove the
... We leave it to the reader to use the above Corollary and our theory developed to this point to show that a0 , b0 , c0 , d0 are the vertices of a rectangle R0 . Let e0 = a0 ; let d0 ∈ s(a0 , b0 ) be such that s(e0 , d0 ) ' s(e, d); and let f 0 ∈ s(a0 , c0 ) be such that s(e0 , f 0 ) ' s(e, f ). Let T ...

To construct a perpendicular bisector: Step 1: Draw 2 arcs with A as the centre and an arbitrary radius on both sides of line AB. Step 2: Draw 2 arcs with B as the centre and the same radius as in Step 1 on both sides of ...
