Across
- 3. _______ - of a triangle, the line segment from any vertex perpendicular to the opposite side.
- 4. - common right triangles in which the angle measures and/or side measures have a special relationship. (30°-60°-90° Right triangles whose acute angles are 30° and 60°.)
- 5. - A new true statement using multiple axioms and theorems.
- 10. - The angle formed on the interior of a closed shape.
- 12. - a ruler without markings, which is used to draw straight lines or check for straightness.
- 13. - A statement that is accepted because it has been proven. (if a transversal intersects two parallel lines, then alternate interior angles are congruent)
- 14. - A geometric transformation over a line that that produces a mirror image of the original object or image.
- 15. - The sum of any 2 sides of a triangle must be greater than the measure of the third side.
- 17. Right Triangle Property:_______________ Congruence - If the hypotenuse and an acute angle of a right triangle are congruent to the hypotenuse and corresponding acute angle to another right triangle, then the triangles are congruent.
- 18. - A geometric transformation consisting of a turn of a shape about a point, often the origin, (0, 0).
- 19. Right Triangle Property: _________ Congruence - If the legs of a right triangle are congruent to the corresponding legs of another right triangle, then the triangles are congruent.
Down
- 1. - A geometric transformation after which the image and pre-image are congruent (length and angle measure are preserved). (Translations, Reflections, Rotations, Glide Reflections)
- 2. – A geometric transformation consisting of a movement to the right or left, up or down, or a combination of movements.
- 6. - A pattern of shapes that fit perfectly together.
- 7. - The sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. That is, a^2+b^2=c^2.
- 8. Right Triangle Property: ________________ Congruence - If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and leg of another right triangle, then the triangles are congruent.
- 9. - Given a line and a point not on that line, there exists a unique line through the point parallel to the given line.
- 11. - triangle with one right angle measuring exactly 90⁰.
- 16. Right Triangle Property: _________ Congruence - If one leg and an acute angle of a right triangle are congruent to one leg and the corresponding acute angle of another right triangle, then the triangles are congruent.
