Pardekooper 6.5 Trapezoids and Kites
Pardekooper 1st, lets look at some theorems • The base angles of an isosceles trapezoid are congruent. Same side interior angles are supplementary
A B D C AC BD Pardekooper 1st, lets look at some theorems • The diagonals of an isosceles trapezoid are congruent.
Pardekooper 1st, lets look at some theorems • The diagonals of a kite are perpendicular. • One of the diagonals is an angle bisector • One pair of angles are congruent
3 2 650 1 Pardekooper OK, here comes a problem. The following is an isosceles trapezoid. Find the measure of the numbered angles. The sum of the angles of a quadrilateral is 3600 1 = 650 650+1+2+3 = 3600 Remember 2 3 650+ 650+x+x = 3600 1300+x+x = 3600 1300+2x = 3600 -1300 -1300 2x = 2300 2 2 2 = 1150 x = 1150 3 = 1150
450 1 3 2 Pardekooper How about another problem. Find the measure of the numbered angles in the kite. 2 = 900 diagonals of a kite are perpendicular 3 = 900 Remember The sums of the angles of a triangle equals 1800 450+ 900+1 = 1800 1350+x = 1800 -1350 -1350 x = 450 1 = 450
