  3. Lines are parallel if they lie in the same plane, and are the same distance apart over their entire length. Parallel Lines If the top and bottom of the boards were not parallel then the boards would not be the same height all the way around the rink. They must be parallel so the boards are even all the way around.

  4. Two objects are congruent if they have the same dimensions and shape. Two Congruent Objects If the two pucks were not congruent then you wouldn’t know if you were playing with a normal sized puck. All pucks should be the same so you are always use the same size.

  5. Vertical Angles Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines. I think the person create these just to put hockey sticks together and to make the picture look better. I don’t think he ever thought about making vertical angles.

  6. A line is perpendicular to another if it meets or crosses it at right angles. Perpendicular Lines If the lines were not perpendicular, then the red line would not be in the middle of the rink. The line would not be straight.

  7. Intersecting lines are two or more lines that meet at a common point Intersecting Lines It is important because if they didn’t intersect, then the lines behind the goal would never stop. If they didn’t intersect then the goalie would not be able to tell how far he can go out of the goal.

  8. Two Angles are Supplementary if they add up to 180 degrees. Supplementary Angles If the angles were not supplementary then they would not add up to 180 degrees.

  9. Corresponding angles are created where a transversal crosses other lines. The corresponding angles are the ones at the same location at each intersection. Corresponding Angles They would not equal the same degrees.

  10. -Two angles that share a common side and a common vertex, but do not overlap. Adjacent

  11. An angle whose measure is greater than 90 degrees but less than 180 degrees Obtuse Angle

  12. A convex polygon whose angles and sides are all congruent Regular Polygon

  13. The angle formed by the equilateral sides of an isosceles triangle Vertex Angle

  14. A triangle with two sides of equal length Isosceles Triangle

  15. A triangle that has a 90 degree angle Right Triangle

  16. The side opposite the right angle in a right triangle Hypotenuse

  17. In a right angled triangle the square of the long side is equal to the sum of the squares of the other two sides. Pythagoras
