Across
- 2. the same triangle a is identical to triangle b
- 5. can be bwh amount of space in a 3D figure
- 7. line cuts shape into congruent parts can be rotational
- 8. It's a chord 2 times the radius
- 9. six faces made of squares
- 11. it goes through two points on a circle not a tangent line
- 12. a/sinA=b/sinB=c/sinC It's a law
- 13. equidistant from the vertices one point
- 16. (a*a)+(b*b)=c*c used for right triangles
Down
- 1. shape inside shape the center is where all angle bisectors meet
- 3. x,y=-x,y x,y=x,-y
- 4. m/v per square foot
- 6. 3 equal sides 3 equal angles
- 8. making shapes smaller p=10 p=5
- 9. V= 3.14*r*r*h SA= (2*3.14*r*r)+(2*3.14*r*h)
- 10. a*a=(b*b)+(c*c)-2bccosA b*b=(a*a)+(c*c)-2accosB
- 11. V=4/3*3.14*(r*r*r) SA= 4*3.14*(r*r)
- 14. half the diameter touches one point on a circle
- 15. four 90 degree angles 4 equal sides
- 17. can be b*h can be b*h/2
