Use a compass and a straightedge together with ∠ above to construct one of the following.
a) Given ∠ is the vertex angle of isosceles ∆, construct ∠.
b) Given ∠ and ∠ are base angles of isosceles ∆, construct ∠.
a) Complete part a) or b) above, whichever you did not do on the test.
b) Construct two different, non-similar isosceles triangles ∆ using ∠ below.

Recall that the Euler Line contains the orthocenter, the centroid, and the circumcenter of a triangle. Construct the Euler
Line for the triangle below, labeling the exact location of the appropriate points of concurrency.
a)
Construct the Euler Line for the triangle below, labeling the exact location of the appropriate points of concurrency.
b) Construct the Euler Line for the triangle below, labeling the exact location of the appropriate points of concurrency.

For the 3 people who do not know, the Deathly Hallows represents the Invisibility
Cloak (equilateral triangle), the Resurrection Stone (circle), and the Elder Wand
(vertical segment) as bestowed upon the three Peverell brothers by Death.
Construct the Deathly Hallows using ̅̅̅̅
 (shown below) as one of the sides of the
Invisibility Cloak. Then give the geometric name for each of the following:
Resurrection Stone: _________________________
Elder Wand: _______________________________

Construct the Deathly Hallows using the circle below as the circle representing the Resurrection Stone.
R
b) Construct the Deathly Hallows using EW below as the segment representing the Elder Wand.
