Across
- 1. the side adjacent to an acute angle
- 3. an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye (the line of sight)
- 6. Triangles if their corresponding angles are congruent and the ratio of their corresponding sides are in proportion
- 8. touching but not intersecting
- 11. Legs legs that are defined as opposite
- 12. Proportionality Theorem one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally
- 13. the function this is equal to the ration of the side opposite a given angle
- 14. Theorem states that the square of the hypotenuse is equal to the sum of the other two sides
- 18. a special type of isosceles right triangle where the two legs are congruent to one another and the non-right angles are both equal to 45 degrees
- 20. Triangle a triangle that has two sides of equal length
- 21. Theorem In a triangle, the segment joining the midpoints of any two sides will be parallel to the third side and half its length
Down
- 2. Angle Theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angle
- 4. Triangle is a triangle in which all three sides are equal
- 5. Legs the leg that is part of the angle
- 7. Angle less than 90 degrees
- 9. the smallest side, 1, is opposite the smallest angle, 30°; while the largest side, 2, is opposite the largest angle, 90°
- 10. the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles
- 13. Right Triangles a right triangle with some regular feature that makes calculations on the triangle easier
- 15. the longest side of a right triangle
- 16. The angle below horizontal that an observer must look to see an object that is lower than the observer
- 17. Triangles a triangle that has an right angle
- 19. expression is defined as any expression containing a radical (√) symbol
