Question

Is it possible to construct a triangle XYZ, where angle X=50°, angle Y=130° and YZ=5cm

Answer 1

no because sum of 2 angle only becomes 180 which isnt possible

Answer 2

no it is not possible to construct such triangle as according to anglesum property of triangle, sum of 3 angles of triangle is 180° bit here sum of only 2 angles X and Y is180
the angle sum property is a property which can be applied to all kind of triangles
in this the sum of all the 3 angles of a triangles is 180

there is another property too but it is not applicable to this situation
