Second, the characteristics of the same internal angle:
1, same side of section line;
2. Sandwiched between two cutting straight lines;
3. The cross section of the inner corner on the same side is U-shaped.
Three, ipsilateral interior angle theorem and inverse theorem:
Theorem:? These two lines are parallel and complementary. The complementary angles add up to 180.
Inverse theorem:? Determination of parallel lines: the internal angles on the same side are complementary and the two straight lines are parallel.

What are the concepts of congruent angle, internal dislocation angle and ipsilateral internal angle?
1. Two straight lines A and B are cut by a third straight line C (or the intersection of C of A and B). On the same side of the cutting line C, cut the corners on the same side of the two straight lines A and B.. We call these two angles congruent angles. ∠ 1 and∠ 5 in the figure are a set of conformal angles. 2. Two parallel straight lines are cut by a third straight line, and the two corners are on both sides of the cutting line and sandwiched between the two cut straight lines. Diagonal lines with this positional relationship are called inscribed angles. ∠4 and∠ 6 in the figure are a set of internal angles. 3. The two angles where two straight lines intersect with the third straight line are on the same side of the cutting line and within the cutting line, which are called ipsilateral inner angles. The inner angle of the same side, "the same side" refers to the same side of the third straight line; "Inside" means between two straight lines cut. In the figure ∠3 and ∠ 6 are a group of internal angles on the same side.

What is the ipsilateral internal angle?
The inner angle of the same side refers to the angle formed by the intersection of two straight lines and the third straight line. For example, in the above figure, A and B are cut by C, and ∠ 1 and ∠2 are called a pair of ipsilateral internal angles. I remember that the second volume of the mathematics textbook of the first day of the Peking University edition will hopefully help you.

What are isosceles angle, medial angle and ipsilateral medial angle?
Two lines are cut by a third line, and the angle of this positional relationship is called congruence angle. The congruence angles are ∠ 1 and ∠5, ∠2 and ∠6, ∠4 and ∠ respectively. 2. Two straight lines are cut by a third straight line, and the two corners are on both sides of the cutting line and sandwiched between the two cut straight lines. Diagonal lines with this positional relationship are called inscribed angles. The inscribed angles are ∠ 3 and ∠ 5, ∠ 4 and ∠ 6 respectively. 3. Two straight lines are cut by a third straight line, between the two straight lines, and

What is the ipsilateral internal angle?
The ipsilateral internal angle is easy to understand, but the ipsilateral definition is not easy to understand. The two angles at which two straight lines intersect with the third line are called inner angles on the same side, which are located on the same side of the cutting line and within the cutting line. The inner angle of the same side, "the same side" refers to the same side of the third straight line; "Inside" means between two straight lines cut. Can read pictures.
