The line segmentthat connects the midpoints of the legs of a trapezoid is called the mid-segment. A. Because of the parallel sides, consecutive angles are same-side interior angles and are thus supplementary. a) Adjacent angles are supplementary. Correct answer: Explanation: The sum of the angles in any quadrilateral is 360 °, and the properties of an isosceles trapezoid dictate that the sets of angles adjoined by parallel lines (in this case, the bottom set and top set of angles) are equal. ... For a trapezoid, two interior angles that inscribe the same leg are supplementary. When two parallel lines are given in a figure, there are two main areas: the interior and the exterior. What is the difference between a trapezium and a trapezoid? Angle: The sum of anglesin a trapezoid-like other quadrilateral is 360°. Why are the two angles on the side of a trapezoid supplementary? Supplementary angles are those angles who add up to 180^@. The angles formed on the same side of a leg (line) are called adjacent angles, and these angles are supplementary. b) Name two angles that are supplementary. Three Midsegments Conjecture.

Property #3) Trapezoids have a midsegment which connects the mipoints of the legs (more) Adjacent Angles of Trapezoid The angles on the same side of a leg are called adjacent angles such as ∠ A and ∠ D are supplementary. Solution. Area formula of a trapezoid equals Area = 1/2 (b1+b2) h h = height. A trapezoid is a quadrilateral. A trapezoid has two parallel sides, and two non-parallel sides. The consecutive angles between the bases of a trapezoid are supplementary. Adjacent angles (next to each other) along the sides are supplementary. [Image will be Uploaded Soon] In this topic we are studying about angle of parallelogram.so the theorem related to the angles are: Opposite angles of parallelogram are equal. What are consecutive angles in a parallelogram? The acute trapezoid has two acute angles (A & D) located on each side of the long base (Line AD) and How can you prove that consecutive angles of a trapezoid are supplementary 2 from MATH 141H at University of Maryland The bases (top and bottom) of an isosceles trapezoid are parallel.
