2: A conjecture is an unproven statement that is based on a pattern or observation. Looking for patterns and making conjectures is a part of a process called inductive reasoning, A counter example is an example that shows a conjecture is false. Terms that cannot be defined are called undefined terms, A point has no dimension. It is represented by a small dot, A line has one dimension. It extends without end in two dimension. Represented by a line with two arrowheads. A plane has two dimension. It is represented by a shape that looks lie a floor or wall.. Then there is Collinear points, Coplanar points, and Coplanar lines. Collinear points are points that lie on the same line. Coplanar points are points that lie on the same plane. Coplanar lines are lines that lie on the same plane. There is also segment AB, endpoints, and rays. Segment AB consists of the endpoint A and B, and all points on AB that are between. The ray AB consists of the endpoints A and all on AB that lie on the same side of A as B.
3: In geometry, figures intersect if they have any points in common. The intersection of two or more figures is the point or points that the figures have in common.The real number that coordinates to a point is the coordinate of the point. THe distance between points A and B is written as AB. It is the absolute value of the difference of the coordinates of A and B. AB is also called the length of AB. | In geometry, segments that have the same length are called congruent segments. An angle consist of two rays that have same endpoint. The rays are the sides of the angles. The measure of an angle is written in units called degrees.
4: Segment bisector- a segment, ray, line, or plane that intersects a segment at its midpoint
5: Midpoint of a segment is the point on the segment that divides it into two congruent segments
6: Bisect- to divide the segment into two congruent segments
7: Angle bisector- a ray that divides an angles into two angles that are congruent
8: April Showers Bring May Flowers | Vertex angles- they are not adjacent and their sides are formed by two intersecting lines | Complementary angle- the sum of their measurements is 90 degrees
9: Supplementary angles- the sum of their measurements is 180 degrees Adjacent angles- they share a common vertex and side
10: Parallel lines- they lie on the same plane and do not intersect Transversal- a line that intersects two or more coplanar lines at different points Corresponding angles- the occupy corresponding position
11: Alternate interior angles- they lie between the two lines on the opposite sides of the transversal | Alternate exterior angles- they lie outside the two lines on the opposite sides if the transversal
12: 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.
13: Two lines are perpendicular if they lie intersect to form a right angle.
14: " | Triangle- a figure formed by three segments joining three non-collinear points Equilateral triangle- 3 congruent sides Isosceles triangle- at least 2 congruent sides Scalene triangle- No congruent sides
15: Equiangular triangle- 3 congruent angles Acute triangle- 3 acute side Right triangle- 1 right angle Obtuse triangle- 1 obtuse angle
16: "Blossom by blossom the spring begins" | Distance formula- gives the distance between two points in a coordinate plane
