Splash Screen

Then/Now You learned about angles (Previous course and Lesson 11-1) You learned about the sum of the angles of a triangle (Previous course) Find missing angle measures of a quadrilateral. Classify quadrilaterals.

Vocabulary quadrilateral A closed figure with four sides and four vertices, examples are squares, rectangles, and trapezoids

Concept

Example 1 Find Angle Measures ALGEBRA Find the value of x in the quadrilateral. Then find each missing angle measure. The sum of the measures of the angles is 360°. Let m  Q, m  R, m  S, and m  T represent the measures of the angles.

Example 1 Find Angle Measures m  Q + m  R + m  S + m  T=360Angles of a quadrilateral x x=360Substitution 5x + 185=360Combine like terms. 5x – 185=360 – 185Subtract 185 from each side. 5x=175Simplify. x=35Divide each side by 5. Answer: So, m  T = 35° and m  R = 4(35) or 140°.

A.A B.B C.C D.D Example 1 A.x = 4; m  A = 4° and m  C = 16° B.x = 5; m  A = 5° and m  C = 20° C.x = 40; m  A = 40° and m  C = 160° D.x = 104; m  A = 104° and m  C = 416° Find the value of x. Then find each missing angle measure.

Quadrilaterals Trapezoids Parallelograms Other Quadrilaterals Rhombus Rectangles Squares

Example 2 Classify Quadrilaterals Answer: parallelogram Classify the quadrilateral shown using the name that best describes it. The quadrilateral has both pairs of opposite sides parallel and congruent.

A.A B.B C.C D.D Example 2 A.square B.rectangle C.rhombus and rectangle D.parallelogram and square QUILT PATTERN The figure shows a pattern for the border of a quilt. Classify the quadrilaterals used to form the flower and the leaves using the name that best describes them.
