Lesson 51-60

1. of an isosceles triangle- the side opposite the vertex angle
6. probability-a form of theoretical probability determined by a ratio of geometric measures such as lengths areas or volumes
9. area-the sum of the areas of a prism or pyramid or the area of the lateral surface of a cylinder or cone
11. angle of an isosceles triangle- one of the two angle that have a base of the triangle as a side
13. prism- a prism whose lateral faces are all rectangular-
15. number of nonoverlapping unit cubes of a given size the will exactly fill the interior of a three dimensional figure
18. right triangle-a 45 45 90 triangle or a 30 60 90 triangle
20. segment of a triangle-a segment that joins the midpoints of two sides of a triangle
21. drawing-a way of drawing three dimensional figures using isometric dot paper which has equally spaced dots in a repeating triangle pattern
22. point perspective-a perspective drawing with two vanishing points

2. area-a total area of all faces and curved surfaces of a three dimensional figure
3. point perspective-a perspective drawing with one vanishing point
4. drawing-a drawing in which non vertical parallel lines appear to meet at one or two points called vanishing points
5. angle of an isosceles triangle-the angle formed by the legs of an isosceles triangle
7. edge- an edge of a prism or pyramid that is not an edge of the base
8. of a prism-a segment that is perpendicular to and has its endpoints on the planes of the bases.
10. of an isosceles triangle-one of the two congruent sides of an isosceles triangle
12. face-a face of a prism or a pyramid that is not a base
14. point-in a perspective drawing a point on the horizon where parallel lines tend to meet.
16. the horizontal line in a perspective drawing that contains the vanishing points.
17. triangle-a triangle formed by three midsegments of a triangle
19. prism-a prism that has at least one non rectangular lateral face
