2: A point has no dimension. It is represented by a small dot. | A line has one dimension. It extends without end in two dimensions. It has represented by a line with two arrowheads.

3: A plane has two dimensions. It is represented by a shape that looks like a floor or wall. You have to imagine that it extends without end. | A real world example of a plane would be a football field, because it looks like a floor.

4: A right angle measures 90 degrees. A real world example would be the corner of a table. | An obtuse angle measures between 90 and 180 degrees.

5: An acute angle measures between 0 and 90 degrees. | A straight angle measures 180 degrees.

6: Angle Bisector- a ray that divides an angle into two angles that are congruent. | A real world example would be the lines on a leaf.

7: Segment Bisector- a segment, ray, line, or plane, that intersects a segment at its midpoint.

8: Two angles are supplementary angles is the sum of their measures is 180 degrees. | Two angles are complementary angles is the sum of their measures is 90 degrees.

9: Two angles are vertical angles if they are not adjacent and their sides are formed by two intersecting lines. | A real world example would be a water tower.

10: Two lines are parallel if they lie in the same plane and do not intersect. A real world example would be road lines. | Two angles are corresponding angles if they occupy corresponding positions.

11: Two angles are alternate interior angles if they lie between the two lines on the opposite sides of the transversal. | Two angles are alternate exterior angles if they lie outside the two lines on the opposite sides of the transversal. | Two angles are same side interior angles is they lie outside the two lines on the opposite sides on the transversal.

12: Two lines are perpendicular lines is they intersect to form a right angle.

13: A real world example would be a compass.

14: Equilateral Triangle- 3 congruent sides | Isosceles Triangle- at least 2 congruent sides | Scalene Triangle- no congruent sides

15: Right triangle- measures 90 degrees. | Obtuse angle- measures between 90 and 180 degrees | Straight angles- measures 180 degrees | Acute angle- measures between 0 and 90 degrees.

16: The Pythagorean Theorem- In a right, triangle, the square of the length of the hypotenuse in equal to the sum of the squares of the lengths of the legs. | A real world example would be a ladder leaning against the wall.

17: The Distance Formula- gives the distance between two points in an coordinate plane.

18: SSS- side side side | SAS- side angle side. Real world example- roller coaster

19: ASA- angle side angle | AAS- angle angle side | HL- hypotenuse Leg

20: Polygon- a plane figure that is formed by three or more segments called lines | A rhombus is a parallelogram with 4 congruent sides | A rectangle is a parallelogram with four right angles

21: A square is a parallelogram with four congruent sides and four congruent angles. | A parallelogram is quadrilateral with both pairs of opposite sides parallel. A real world example of would a guitar.

22: 1. Skew lines- two lines that do not line on the same plane 2. Converse- the statements formed by switching the hypothesis and the conclusion. 3. Construction- a geometric drawing that uses a limited set of tools. 4. Vertex- a point that joins two sides of a triangle. 5. Legs- the congruent sides of an isosceles triangle

23: 6. Base- the other side of an isosceles triangle 7. median- a segment from a vertex to the midpoint of the opposite sides. 8. Centroid- the tree medians of a triangle that intersect at one point 9. adjacent angles- share a common vertex and sides, but have no common interior points 10. Theorem- a true states that follows from other true statements.
