4. Which of the following is a property of a Definition of isosceles trapezoid in the Definitions.net dictionary. Meaning of isosceles trapezoid. What does isosceles trapezoid mean?

It is a geometric figure with 4 sides and 4 vertices, the isosceles trapezoid has 2 parallel sides and will always have diferent lengths betwen them; the other two sides are equal length. The isosceles trapezoid in its bigger base has equal angles, and in its smaller base has also equal angles. Area Definition 2010-03-31 · To find the length of the median, you must find the average of the base lengths (base + base / 2 = median) so: 14 + 20 = 34.

Angles are calculated and displayed in degrees, here you can convert angle units. Side lengths, diagonal, 2016-01-03 · In a isosceles trapezoid, if its equal sides are extended, we get an isosceles triangle whose base is the bigger base of the trapezoid. In a isosceles triangle, the angles with the base, #alpha# and #beta#, are congruent (#alpha=beta#). Since the segments P2P3 and P1P4 are parallel (from the definition of trapezoid), by the Alternate Interior Angles Theorem we can conclude that #gamma=180^@-alpha# and #delta=180^@-beta#; since #alpha =beta# then #gamma=delta#.
