|1.||Construct an isosceles triangle whose base is equal in length (congruent to) the segment FG, and whose legs are congruent to AB.|
|2.||(a)||Construct two isosceles triangles with base CD and legs AB, which share a common base,
as shown in the example.
|(b)||The leg and base lengths are in the ratio of 1 : √2. What are the measures of all 6 interior
angles in the finished construction?
|(c)||Confirm this by measuring them with a protractor, and explain this result.|
