1: Table of Contents
2: The intersection of two or more figures is the point or points that the figures have in common. | A plane is a flat surface on which a straight line joining any two points on it would wholly lie. | Distance is the amount of space in between to places or things.
3: Real world examples
4: Angles and their measures | Acute~ an acute triangle is between 0 and 90 degrees | Right~ A right triangle can only be 90 degrees | Obtuse~ from 91 to 180 degrees
6: Segment bisector~ a segment, ray, line or plane that intersects a segment at its midpoint | Angle bisector~ a ray that divides an angle into two angles that are congruent
8: Complimentary angles~ angles that add up to be 90 degrees
9: Vertical angles~ two angles that are not adjacent and their sides are formed by two intersecting lines
10: Parallel lines and angles formed by transversals Two lines are parallel lines in the same plane and do not intersect. A transversal is a line that intersects two or more coplaner lines at different points. Two angles are corresponding angles if they occupy corresponding positions. Two angles are alternate interior angles if they lie in between the two lines on the opposite sides of the transversal. Two angles are the same interior angles if they lie between the two lines on the same side of the transversal.
12: Perpendicular lines If two lines are perpendicular then they intersect to form four right angles
14: Equiangular triangle is 3 congruent sides Isosceles triangle at least two congruent sides Scalene- no congruent sides
15: Definition of Triangles, Angle Measures, Names of Triangles | A triangle is a figure formed by three segments joining three non-collinear points. A triangle can be classified by its sides and by its angles | A vertex of a triangle of a triangle is a point that joins two sides of the triangle. The side across from an angle is the opposite angle.
16: Pythagorean theorem- The area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs
17: Distance formula-
18: Polygons: | Parallelograms- A quadrilateral with both sides parallel | Rhombus- parallelogram with four congruent sides | Rectangle- Parallelogram with four right angles
19: Square- Parallelogram with four right angles and four congruent sides | trapezoid- a quadrilateral with exactly one pair of parallel sides
