Polygons and Quadrilaterals
A Kite is a quadrilateral with 2 pairs of consecutive congruent sides and no opposite congruent sides and its diagonals are perpendicular.
Explanation for above problem^^
A=90 because when a kites diagonals cross, they bisect each other at 90 degrees. C is 47 because the angle across from it is corresponding, so they are the same. B=43 because 90 plus 47 plus 43 equals 180.
Trapezoids and Isosceles Trapezoids
Both regular trapezoids and isosceles trapezoid have two parallel sides. The only difference between the two is that an isosceles trapezoid has legs that are congruent and base angles that are also congruent.
