An explanation of a trapezoid as a quadrilateral with exactly one pair of parallel sides. Each of the parallel sides is called a base, and the nonparallel sides are called the legs. Base angles of a trapezoid are two consecutive angles whose common side is a base. If the legs of a trapezoid are congruent, the trapezoid is an isosceles trapezoid. We have three theorems for the Properties of Isosceles Trapezoids, we find an angle measure, and then a side length, using the properties of Isosceles trapezoids, we find the value of a variable so that a trapezoid is isosceles. We discuss the mid-segment of a trapezoid as the segment whose endpoints are the midpoints of the legs. We discuss the Trapezoid Mid-segment theorem and use it to find the length of a base. We compare the Trapezoid Mid-segment theorem to the Triangle Mid-segment theorem to see the difference between their formulas. • High School Geometry Playlist • • High School Geometry Course • Geometry 6.6b, Isosceles Trapezoids Midsegment of Trapezoids 4 Theorems • • Geometry 6.6b, Isosceles Trapezoids ... • FOLLOW ME: • TWITTER / joannsschool • FACEBOOK Message me! / joannsschool • MINDS Minds.com/joannsschool • SUPPORT MY WORK: • PATREON / joannsschool • PAYPAL https://www.paypal.com/cgi-bin/webscr... • YOUTUBE / @joannsschool • Get a JoAnn's School t-shirt, mug, tote, hoodie, • or inspirational sticker to let everyone know you're a fan! • Teespring.com/joann-s-school-t-shirts
