Across
- 3. - the same, if a sequence of rigid motions and dilations that takes the first figure onto the second
- 6. - a solid figure that has one special face called the base. All the other faces are triangles that meet at a single vertex called the apex.
- 7. - a quadrilateral with four right angles. Each right angle is 90 degrees
- 10. - a solid figure composed of two parallel, congruent faces connected by parallelograms. A prism must include flat sides.
- 11. - a cone is a three dimensional figure with a circular base and a point on the base is connected to the apex by a line of segment. An example of a cone is a traffic cone.
- 12. - a three dimensional figure with two parallel, congruent, circular bases, formed by translating one base to the other. Each pair of corresponding points on the bases is connected by a line segment Rhombus - A quadrilateral with four congruent sides. Also known as a diamond.
- 14. angle - an angle formed by two rays whose endpoints are the center of a circle. The radius vectors from from the arms of a central angle
- 15. - the region inside a circle lying between two radii of the circle. Think of a pie slice
- 16. quadrilateral - a quadrilateral whose vertices all lie on the same circle. Also known as a inscribed quadrilateral
Down
- 1. - an arrangement of figures that covers the entire plane without gaps or overlaps, have done this in class
- 2. - two lines that don't intersect are called parallel. We can also call segments parallel if they extend into parallel lines.
- 3. - a three dimensional figure in which all cross sections in every direction are circles. Basketball is an example.
- 4. - The part of a circle lying between two points on the circle. Two arcs have congruent angles.
- 5. of symmetry - a line of symmetry for a figure is a line such that reflection across the line takes the figure onto itself. A vertical line down the middle of a heart would be a line of symmetry.
- 6. bisector - a line through the midpoint of the segment that is perpendicular to it. It divides the segment right at the midpoint Rigid Transformations - a translation, rotation, or reflection. These are mainly used on the coordinate plane
- 8. of rotation - A line about which a two dimensional figure is rotated to produce a three dimensional figure, called a solid of rotation. Also known as axis of revolution
- 9. - a statement that has been proved mathematically, pythagorean _______
- 13. - the mass of a substance per unit volume. Helps to determine the volume of an object
