Issue for Learning Geometry Quadrilaterals

To show that the sum of the five angles of a quadrilateral is 360°geometry problems solved.

Solution online geometry answers:

Let PQRS be the given quadrilateral.

They must show that P + Q + R + S = 360°.

Sketch the diagonal PR. From the triangles PRS and PQR, they get

SPR+ S + PRS = 180°

RPQ + Q + PRS = 180°

SPR + S + PRS + RPQ + Q + PRQ = 360°

(SPR + RPQ) + Q + (PRS + PRQ) + S = 360°

P + Q + R + S = 360°.
