Across
- 2. A straight line that touches a circle at only one point. This point is called the point of tangency.
- 4. an arc that measures more than 180. It is also less then 360 and is found by 360 minus its associates minor arc (uses 3 letters)
- 7. An angle whose vertex is on the circle and sides contain chords. The measure of an inscribed angle is 1/2 of the measure of its intercepted arc.
- 8. A straight line that intersects a circle. It intersects at exactly two points
- 12. The sum of the areas of all of the faces. This does include the bases.
- 14. Name a shape with 3 sides. All angles add up 180.
- 15. A line segment throughout the entire circle passing through the center. This is double the length of the radius.
- 16. A quadrilateral having only one pair of parallel sides. The sides that are parallel are called the bases and the non- parallel sides are called the legs.
- 19. A straight line from the center of a circle to its circumference. This is half of the circle diameter.
Down
- 1. Name a shape with 8 sides. This is the shape of a stop sign.
- 3. Points in the original figure move an identical distance along parallel lines. A distance and direction are needed.
- 5. The amount of space that a two dimensional object occupies. For example, the equation to find the _____ of a square is l x w.
- 6. an arc that measures less than 180. It is equal to the measure of its central angle (uses only 2 letters)
- 9. A four sided figure. Some examples are parallelograms, squares, and rectangles
- 10. The sum of the areas of the lateral faces. It does not include the bases.
- 11. Name a shape with 5 sides. All angles are add up to 360
- 12. A round solid figure and every point on its surface is an equal distance from its center. For example a ball.
- 13. The exact middle point in a line segment. This point bisects the segment.
- 17. A 3 sided figure with two sides that are the same length. The base is not the same length as the two legs.
- 18. Lines that are coplanar and are the same distance apart. These lines will never intersect.
