Quadrilaterals Day 1 (of 5) The basics: A quadrilateral is: a closed geometric figure with 4 sides and 4 angles. The segments (sides) intersect only at the endpoints and its angles add to 360°

Convex Concave “caved in” In this section, we’re going to study CONVEX quadrilaterals.

Consecutive v Nonconsecutive In a rowNot in a row - “opposite” in quadrilateral speak A D C B Segments AD and DC are consecutive sides Segments AD and BC are nonconsecutive sides – or “opposite” sides Angles A and B are consecutive angles Angles B and D are nonconsecutive angles – or “opposite” angles.

You need a protractor and a piece of patty paper for this exercise.
