Question

conclusion of angle sum property of polygons:triangle, quadrilateral, pentagon​

Answer 1

Answer:

The sum of angles in a triangle is 180 °. This means that the sum of angles in a hexagon is equal to 4 × 180° that is 720°. Similarly, in figure b which is a pentagon, the number of triangles constituting the shape is three, so the sum of angles in a polygon shall be 3× 180 which equals 540°.

Answer 2
