Across
- 2. (x-h)2+(y-h)2+r2 where r=radius and (h,k) is the center
- 4. a2=b2+c2-2bc(cosA) b2=a2+c2-2bc(cosB) c2=a2+b2-2ab(cosC)
- 6. the angle that an upward line of sight makes with a horizontal line
- 7. c2>a2+b2=obtuse c2<a2+b2=acute c2=a2+b2=right
- 8. a segment from a vertex of a triangle to the midpoint of the opposite side
- 10. the segment that connects the midpoint
Down
- 1. the angle that a downward line of sight makes with a horizontal line
- 3. a ratio of the lengths of 2 sides in a right triangle
- 5. a segment that connects the midpoint of a sides of a triangle
- 9. of sines SinA/a = SinB/b = SinC/c = a/SinA = b/SinB = c/SinC
