What is the Outer Angle What is the Inner Angle

Inner Angles: The three corners inside the triangle are the interior angles of the triangle.

Precise definition: The angles of the two sides of the triangle with one vertex of the triangle as its vertex and the two sides of the triangle passing through the vertex (but not the reverse extension line) as its two sides are the inner angles of the triangle.

For example, two 45° angles and one 90° angle of a symmetrical triangle are internal angles;

The angles of 30°, 60°, and 90° of the asymmetrical triangle are all internal angles;

But don't get me wrong, you can only be the inside angles of these degrees, and any angle of any degree is the inside angle of a triangle as long as it satisfies precisely defined conditions.

Outside Angle: Precise definition of the outside angle: (for triangles).

The outer angles of the triangle are the outer angles of the triangle with one side of the triangle past the vertex and the opposite extension of the other side of the triangle past the vertex as its vertex.

Inner corner, overview of the outer corner.

Extending all three sides of the triangle to both sides, we can find that all 3 * 4 = 12 corners, three of which are exactly opposite to the three inner angles of the triangle, equal in size, they are the opposite vertex angles of the three inner angles, and after excluding the three inner angles and their three opposite vertex angles (3+3=6), there are 6 corners left, and they are all the outer angles of the triangle. Each outer angle adds up to 180 degrees to the inner angle adjacent to it, which is a complementary angle.

Because I can't draw pictures on a computer, I can only describe it to you.

Draw a triangle abc, the angle between ab and ac is called the inner angle, extend ba to the outer point of the triangle and set it to e, the angle between ae and ac is called the outer angle, and the outer angle is the angle that is not complementary to the inner angle.

A closed figure consisting of three line segments that are not on the same line is connected by a grasp and a mind, which is called a triangle. The figure enclosed by three straight lines on the plane or three arcs on the sphere, and the figure enclosed by the three straight lines is called a plane triangle; The shape enclosed by three arcs is called a spherical triangle, also known as a trilateral.

The closed geometry is obtained by connecting three collapsing line segments end to end.

It's called a triangle. A triangle is the basic shape of a geometric pattern.

The relationship between the outer and inner angles is as follows.
