View HintsThe sum of interior angle and exterior angle is \\(180^{\\circ}\\) \\((n-1)\\times 110^{\\circ} + 100^{\\circ} = (n-2)\\times 180^{\\circ}\\) any point lying on one line will also be lying on the other as well \\(4x + 40^{\\circ} = (n - 2)\\) boundary contaning lines as well as curves Sides opposite equal angles of a triangle are equal All the angles of a convex quadrilateral measure less than \\(180^{\\circ}\\) Orthocentre is the intersection point of altitudes name defined to close figure made by joining 3 line segments Reflex angle is > \\(180^{\\circ}\\) and < \\(360^{\\circ}\\) |
