Geometry vocabulary
Across
- 2. two lines on the same plane that will never meet.These lines will always be the same distance apart.
- 3. A line that splits another line into two right angles. This line is always right in the middle of the line.
- 6. The equation to find this is opposite over hypotenuse. You use this equation on right triangles
- 7. The equation for this is y=mx+b. You use this equation to find how steep a line is.
- 14. This is the relationship between two numbers. This is often written like x:y.
- 15. This is an angle with a degree greater that 90. This is also another way to describe a triangle.
- 16. A line that runs up and down.This runs the other direction of a horizontal line.
- 19. The equation for this is opposite over adjacent. You would use this equation on right triangles.
- 20. To move around a certain point on a graph. The image would move around this point on a 360 degree.
Down
- 1. A line that runs side to side. This line runs the other direction of a vertical line.
- 4. The equation for this is adjacent over hypotenuse. You use this equation on right triangles.
- 5. The equation of this is (x1+x2/2,y1+y2/2). This helps fine the middle of a line.
- 8. This is two figures that are the same shape and size. This can also be two lines that are the exact same length.
- 9. A triangle with two equal sides. This will cause two of the angles to be the same degree.
- 10. This is an angle with a degree less than 90. This is also another way to describe a triangle.
- 11. A flip over the y or x axis. If you were to fold a paper in half the image would be the same.
- 12. The line that passes through two parallel lines. This line creates many different angle pairs.
- 13. The equation for this is y-y1= m(x-x1). This helps you find the slope of a line at a certain point.
- 17. A triangle where all sides are different lengths. You can identify this triangle if all the angles are different measures.
- 18. The long side of a right triangle. This line is opposite of the right angle.
