The sum of the angles of a quadrilateral is 360°. Find the conditional, draw a diagram, and state the given and conclusion.

CONDITIONAL FORM: If it is the sum of the angles of a quadrilateral, then it measures 360°.

DIAGRAM: Not shown, but pictures a trapezoid with angles A, B, C, and D.

CONCLUSION: ∠A + ∠B + ∠C + ∠D = 360°.
