Point: Point is the simplest and most basic element in geometric figures. It has no size, shape, or orientation, only the concept of position. A line is formed by infinite extension of countless points and has the concepts of length, direction and position.
Wire
straight line
Two points establish a straight line
Rays
Two rays form an angle
flat angle
180 degree
right angle
90 degrees
acute angle
Greater than 0 degrees and less than 90 degrees
obtuse angle
Greater than 90 degrees and less than 180 degrees
angle relationship
adjacent supplementary angle
There is a common side and complementary angles
supplementary angle
The sum of two angles is 180 degrees
remaining angle
The sum of two angles is 90 degrees
Vertical angle
Vertical angles are equal
Isotopic angle
Two straight lines are intercepted by a third straight line, and a pair of angles at the same position
Internal offset angle
A pair of angles where two straight lines are intercepted by a third straight line, and both angles are between the two straight lines and intersected.
Internal angle on the same side
Two straight lines are intercepted by a third straight line, both angles are between the two straight lines, and a pair of angles on the same side of the third straight line
line segment
The shortest line segment between two points
line relationship
vertical
Perpendicular axiom: There is and is only one straight line perpendicular to a known straight line through a point in the same plane.
The vertical segment is the shortest
parallel
Parallel Axiom: There is one and only one straight line passing through a point outside the straight line that is parallel to the known straight line.
The concept of parallel lines: Two straight lines that never intersect in the same plane are called parallel lines, represented by "//"
Parallel axiom corollary: Two straight lines parallel to the same straight line are parallel
Judgment of parallel lines: If the same angles are equal, the two straight lines are parallel; if the interior angles are equal, the two straight lines are parallel; if the interior angles on the same side are complementary, the two straight lines are parallel;
Properties of parallel lines: Two straight lines are parallel, and the angles on the same side are equal; two straight lines are parallel, and the interior angles on the same side are equal; two straight lines are parallel, and the interior angles on the same side are complementary;
intersect
Surface: It is an area bounded by one or more lines and has area and shape.
