Geometry

1. A type of angle. Equal to 90 degrees.
2. Connects two points. Continues on forever.
3. Something that splits something in two. This includes lines, segments and rays.
5. Belonging to the same plane. Can include lines an points.
7. Consists of two lines. The lines never intersect.
8. The longest side of a triangle. This side is opposite of the right angle.
12. A type of angle. Smaller than 90 degrees.
14. A type of triangle. All of its sides are equal.
15. A type of angle. Bigger than 90 degrees.
18. Similar to a line. Continues infinitely in ONLY one direction.
19. A type of triangle. None of its sides are equal.
20. A 2D flat surface. Named with a capital letter.

1. A line segment going from the center to a point on a circle. It is half the diameter.
4. A type of triangle. Only two of its sides are equal.
6. When two lines intersect. The angle formed is 90 degrees.
9. Has 4 equal sides. This is a basic shape.
10. Points that belong to the same line. Usually three of more points are present.
11. A line running through the center of a circle. It is 2x the radius.
13. Has 5 sides. Usually contains two obtuse angles and three acute angles.
16. An infinite shape with no sides. It is 360 degrees.
17. Made entirely of straight lines. A closed figure.
