Isosceles Triangles Today! Take a second and see if you can remember the difference between Isosceles and Equilateral.

1. Open up Blackbeard's newly captured slave ship again in Sketchup. If the mizzensail (rear sail) is an isosceles triangle, then what can be said of the legs (the two long sides)? What can be said of the base angles (the two angles toward the back of the ship)?

2. Read 4-6

3. In 4-6, work problems 2-28 even, 44, 50, 52.

Extra Credit: # 30 (first step – congruent triangles), 34, 36, 38, 42.
