In this lesson our instructor talks about trapezoids and kites. First she discusses the definition of trapezoid and isosceles trapezoid. The she talks about median of a trapezoid. Lastly, she lectures on kite and does a quadrilaterals summary. Four complete extra example videos round up this lesson.
Trapezoid: Quadrilateral with exactly one pair of parallel sides
Isosceles trapezoid: Trapezoid with congruent legs
Both pairs of base angles of an isosceles trapezoid are congruent
The diagonals of an isosceles trapezoid are congruent
The median of a trapezoid is the segment that joins the midpoints of its legs
The median of a trapezoid is parallel to the bases, and its measure is one-half the sum of the measures of the bases
Kite: Quadrilateral with two pairs of adjacent congruent sides
