3. Parallel Lines
Lines are parallel if they lie in the same plane, and are the same distance apart over their entire length.
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 Congruent Objects
Two objects are congruent if they have the same dimensions and shape.
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. Perpendicular Lines
A line is perpendicular to another if it meets or crosses it at right angles.
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
Intersecting lines are two or more lines that meet at a common point
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. Supplementary Angles
Two Angles are Supplementary if they add up to 180 degrees.
If the angles were not supplementary then they would not add up to 180 degrees.

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

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

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

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

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

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

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

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

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