2: Line: A line has one dimension and extends without end in two directions. It is represented by a line with two arrowheads. | Geometry | Example: Lines of Latitude | Ray: A ray is a vertex that has a never ending line coming from it. | Example: A Laser Pointer

3: Basics | Point: A point has no dimension. It is repressed by a small dot. | Example: A button

4: Angles and Their Measures | Angle: An angle consists of two rays that have the same endpoint. | Example: An angle between a building and a ladder | Sides: The rays of the angles are the sides. | Examples: The side of a mountain

5: Example: The tip of a mountain | Vertex: The point of an angle is called a vertex.

6: Angles and Their Segment Bisectors | Angle Bisectors: An angle bisectors is a ray that divides an angle onto two angles that are congruent. | Example: The twister handle on a square timer

7: Midpoint: The midpoint of a segment is the point on the segment that divides it into two congruent segments. | Example: The intersection of a plus | + | Bisect: To bisect a segment is to divide the segment into two congruent segments. | Example: The intersection of a cross

8: Complementary, Supplementary, and Vertical Angles | Complementary Angles: A complementary angle is when the sum of two angles measures is 90 degrees. | Example: A circular clock at three o'clock and 7 and half minutes

9: Supplementary Angles: A supplementary angles is when the sum of two angles measures is 180 degrees. | Example: When a circular clock is at 3:45 | Vertical Angles: A vertical angles is when two angles that are not adjacent and their sides are formed by two intersecting lines | Example: Scissors

10: Parallel Lines and Angles formed by Transversals | Parallel Lines: Parallel lines are two lies that lie in the same plane and don't intersect. | Example: Train tracts

11: Parallel Planes: Parallel planes are two planes that don't intersect | Example: Bookshelves | Tr | Transversal: A transversal is a intersecting a system of line | Example: A Bike

12: Perpendicular Lines | Line Perpendicular to a Plane: A line perpendicular to a plane is a line that intersects a plane in a point and that is perpendicular to every line in the plane that intersects it. | Example: The beams of a house

13: Example: A box | Perpendicular lines: Perpendicular lines are two lines that intersect to form a right angle. | Skew Lines: Skew lines are two lines that don't lie on the same plane and never intersect. | Example: The things that hold up banisters

14: Triangles | Triangle: A triangle is a figure that is formed by three segments joining three noncollinear points | Example: A piece of cake | Acute Triangle:

15: Equilateral Triangle: An equilateral triangle is a triangle with 3 congruent triangles | Scalene Triangle: A scalene triangle is a triangle that has no congruent sides. | Example: Yield sign | Example: A cat's ear

16: Pythagorean Theorem | Legs: In a right triangle, the sides that form the right angle are called the legs. | Hypotenuse: The side opposite of the right angle is the hypotenuse. | Example: A building | Example: A ladder on a building

17: The Pythagorean Theorem: In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs is the Pythagorean Theorem equation. | Example: When your trying to figure out the difference between a ladder and a building

18: Congruent Triangles | Corresponding Parts: Corresponding angles and corresponding sides are examples Corresponding parts. | Example: A kite

19: Congruent: Figures are congruent if all pairs of corresponding angles are congruent and all pairs of corresponding sides are congruent | Example: Floor tile | Example: Triangle EFG is congruent to Triangle HGI | Proof: Proof is a convincing argument that shows why a statement is true.

20: Polygons | Polygons: A polygon is a plane figure that is formed by three or more segments. | Example: Triangle

21: Sides: A side is a segment on a polygon | Example: A ladder | Vertex: The endpoint of a polygon is a vertex | Example: The edge of a ladder
