Across
- 3. Any number we can write as a decimal number. This is between 1.0 and 10.0, multiplied by a power of 10.
- 6. The sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse. Could also add up the two sides to get hypotenuse.
- 8. A triangle that has all three sides that are all the same length. Also, all three angles are the same size, too.
- 9. An acute angle triangle where all three interior angles are less than 90 degrees. A type of triangle with the angles and sides equal to each other.
- 12. A line perpendicular to a surface. Could also be perpendicular to another line considered as a base.
- 13. A type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. This is a circular movement.
- 14. A triangle that has three unequal sides. The sum is still 180 degrees.
- 15. A triangle that measures less than 90 degrees. This is the smallest angle.
- 16. A line that goes from left to right across the page. It is also parallel to the x-axis.
- 18. The equation of a straight line in the form y = mx+b. 'M' is the slope of the line, and b is its y-intercept.
- 19. A triangle that measures more than 90 degrees. It is also less than 180 degrees.
- 20. Expression that gives the distance between pairs of points in terms of their coordinates. Measures how far two objects are.
Down
- 1. The longest side of a right triangle. It is opposite the right angle.
- 2. A type of transformation that takes each point in a figure and slides it the same distance in the same direction. An example could be "5 units right and 2 units up"
- 4. Two figures or objects that have the same shape or size. The measures and angles are identical.
- 5. A mirror image of a function or object over a given line in the plane. Can also be described as a "flip"
- 7. Lines on a plane that are always the same distance apart. This is no matter what direction.
- 10. The formula to find the center point of a straight line, using the coordinates of its endpoints. The middle of a line segment.
- 11. A triangle with at least two equal sides. The two sides are called legs.
- 17. Two lines that intersect at a right angle. The slopes are negative reciprocals of each other.
