Triangles Vocabulary

7. The “bottom” of the triangle. Any side can be a base, and it will be perpendicular to the height.
11. angles that add up to 90 degrees
13. The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
17. angles that add up to 180 degrees
18. A squared plus B squared equals C squared
19. the perpendicular line drawn from the vertex of the triangle to the opposite side. Also, known as the height of the triangle
21. The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the adjacent side.
22. a rigid motion that moves points the same distance and direction
23. the two sides of a right triangle that intersect to determine the right angle.
24. when two triangles have the exact same angles they are said to be
25. angle formed by a horizontal line and the line of sight to an object above the horizontal line

1. measure of the smallest, positive, acute angle formed by the terminal side of the angle and the x-axis.
2. the sum of the angles in a triangle
3. The name of the professional ice hockey team in Detroit. Mr. Holt's favorite team.
4. The final position of a line which was rotated. Also the line that tells us the degree when using a protractor.
5. change in the size, shape, or position of a geometric figure. Like Optimus Prime.
6. Mr. Holts favorite number
8. A hypotenuse is the longest side of a right triangle, the side opposite the right angle.
9. The trigonometric function that is equal to the ratio of the side adjacent a given angle (in a right triangle) to the hypotenuse.
10. the month Mr. Holt was born in
12. A triangle with one angle that measures 90 degrees
14. a tool used to measure angles
15. When two triangles have the same side lengths and same angle measurements they are said to be...
16. Top ten math teacher at this school.
20. the act of making a figure bigger or smaller
