10-5 Quadrilaterals Indicators  G2a- Determine one set of figures is a subset of another G2b- Develop a set of properties that eliminates all but the desired figure Pages 434-437

Quadrilaterals- Closed figure with four sides and four angles Quadrilaterals are named based on their sides and angles. Most Specific    Most General Quadrilaterals 4-sided figure Parallelogram 2 pair of ׀׀ sides Trapezoid 1 pair of ׀׀ sides Rhombus & 4 congruent sides Rectangle & 4 right (90º) angles Square Is a rectangle & a rhombus = = = = ׀ ׀ ׀׀ ׀ ׀ ׀ ׀ ׀ ׀ ׀ ׀

Angles of a Quadrilateral The sum of the measures of the 4 angles in any quadrilateral is 360 º. 1 2 3 4

Classify the quadrilateral Classify the quadrilaterals using the name that BEST describes the figure.

Find the missing measure Find the missing angle measure in the quadrilaterals. 60 º 120 º xºxº 108 º 115 º 73º xºxº
