Abstract

DC60 (19/12/56) Mathematics Set A triangle with an angle that follows the side of the approach angle. Is a medium used by teachers in Classroom teaching Which looks like a square wooden board With rectangular wooden frame On a square wooden board is screened as a scalene triangle. And there is a screen line following the Of the approach angle on the right-hand side of the scalene triangle And there is a block showing the left corner of the picture Triangle to insert 1 corner plank and 1 corner plank block to insert 1 corner plank player and make outside corner blocks connected from the sides of the angle. To the right-hand side of the scalene triangle To insert the player, 1 piece of wooden corner Colored angles on both sides The player can be removed from the block and can be turned over. Which size of the player The corner plank of the left corner of the triangle Combined with the player, the angle of the upper corner of the triangle is the same size as the angle plank player on the right-hand side of the asymmetrical triangle to describe and show the relationship of the triangle with its angles. Following the corner of the corner, the corner plank is used to form the corner of the left corner of the triangle with the corner plank player. The top of the two triangles represents the size of the player's corner. On the right-hand side of the triangle, the opposite sides fit each other. Which this invention is suitable for Use as a material for teaching mathematics in the classroom Triangles and angles that go from the sides of the adjacent angles and facilitate teachers in choosing to use mathematical materials used in teaching and learning. Correct classes build students' understanding of the proof of theory from concrete to abstract. Is a quality medium according to the principles of mathematics The material is strong, durable, low cost and reduces the time required to fabricate the material multiple times and is easy to store, fostering creativity and a positive attitude in mathematics learning. Student Mathematics learning materials Set of triangles with opposing angles of approach angles Is a medium used by teachers Classroom teaching Which looks like a square wooden board With rectangular wooden frame On square wooden paper is screened as a triangle. And there is a screen line following the Of the approach angle on the right-hand side of the scalene triangle And a left corner block of the triangle was made to insert 1 corner slider and one corner block of the triangle was made to insert 1 corner slider and an outside corner block was made. That continues from the angle of the approach On the right-hand side of the scalene triangle To put 1 piece of angle plank sail, in which the plank sail Colored angles on both sides The player can be removed from the block and can be turned over. Which size of the player The corner plank of the left corner of the triangle Combined with the angled plank sail of the top of the figure Triangles are the same size as the angle plank player of the angle to the right-hand side of the asymmetrical triangle.To describe and show the relationship of the triangle with the angle that follows the angle of the approach angle, the player's placement is used. It is a plank in the shape of the left corner of the triangle. With the corner of the corner wooden player The top of the two triangles replaces the dimensions of the angle plank. To the right-hand side of the scalene triangle That can be replaced Which this invention is suitable for Use as a material for teaching mathematics in the classroom Triangle With the angle that continues from the side of the adjacent corner and facilitates the teachers in choosing to use mathematical materials used in teaching Classes are correct and appropriate, build students' knowledge and understanding in creating knowledge that proves the truth from concrete to abstract. It is a medium of quality that must follow the principles of mathematics. Materials that are strong, durable, lower costs and the time it takes to create media multiple times and conveniently store them, promote creativity and a great direction in mathematics for learning.
