中学数学公式（Middle school mathematics formula） Middle school mathematics formula 1 there is only one line after two 2 the line between two points is the shortest 3 the same angle or isometric equal margin 4 with the angle of the complement of equal or constant 5 having only one line and perpendicular to the known line 6, the line outside a point and the line on all points connected by the line, the vertical line segment is the shortest 7 parallel axioms follow a point outside the straight line and have only one line in parallel with the line 8 if the two lines are parallel to the third lines, the two lines are parallel to each other 9 corresponding angles are equal, the two parallel lines 10 alternate angles are equal, the two parallel lines 11 complementary interior angles on the same side, two parallel lines 12 the two parallel lines, corresponding angles are equal 13 two line parallel, alternate angles are equal 14 the two parallel lines, complementary interior angles on the same side The sum of 15 sides of a triangle is greater than third 16 infer that the difference between the sides of a triangle is less than third 17 triangle triangle sum theorem three angles and equal to 180 degrees 18 inference 1 the two acute angles of right triangle overlap each other 19 a corollary of a triangle is equal to the 2 corners and two angles it is adjacent and 20 a corollary of a triangle with 3 corners than any one and it is not adjacent. The corresponding sides of 21 congruent triangles and equal angles 22 edge axioms (SAS) are congruent with two triangles of equal angles on both sides and their angles 23 corner corner axiom (ASA) has two triangles congruent horns and their edges corresponding to the equal 24 inference (AAS) had two horns and one of the angle on the side corresponding to the equal two congruent triangles 25 side axioms (SSS) having two equal triangles equal to three sides 26, bevel and right side axioms (HL) have two sides of a right triangle corresponding to the
