Question

conclusion of angle sum property of triangle and quadrilateral and polygon​

Answer 1

Answer:

a) conclusion of angle sum property of triangle :

the sum of any three angles of a triangle is equal to 180°

d) conclusion of angle sum property of quadrilateral:

we can divide any quadrilateral into two triangles. total angles of a triangle equal to 180°, so 180° + 180°= 360° so the quadrilateral is equal to 360°

c) the sum of interial angles of a polygon is depend on the number of sides but the sum of the exterior angles is always 360°
