Across
- 4. A triangle with all sides and all angles equal
- 6. A straight line extending from the center of a circle or sphere to the circumference or surface
- 8. A triangle with one right(90) angle.
- 10. Either of the two parallel sides of a trapezoid
- 11. A 90 degree angle
- 12. The "if" and "then" parts of a sentence are switched.
- 14. A trapezoid with base angles that are the same. Consequently, the legs will be congruent together as well
- 17. A scalene triangle is a triangle with all three sides unequal.
- 19. A connected section of the circumference of a circle
- 20. If angle A is an acute angle in a right triangle, the tangent of A is the length of the side opposite to angle A divided by the length of hte side adjacent to angle A.
Down
- 1. A plane figure with the same size and shape
- 2. States that if you have a right triangle, then the square built on the hypotenuse is equal to the sum of the squares built on the other two sides.
- 3. Two line segments which cross to form 90 degree angles
- 5. The point where the three medians meet
- 7. A line segment connecting a vertex to the line containing the opposite side and perpendicular to that side
- 9. A cylinder with bases that are not aligned one directly above the other
- 13. Angles opposite one another at the intersection of two lines.
- 15. The line segment between two points on a given curve
- 16. When two triangles have corresponding angles that are congruent as shown below, the triangles are similar
- 18. A trapezoid is a quadrilateral that has one pair of opposite sides that are parallel
