The base angles are the same. An isosceles trapezoid which is also a right trapezoid is a rectangle. An isosceles trapezoid has an axis of symmetry - the line of symmetry goes through the midpoints of the bases. But an isosceles trapezoid has no rotational symmetry (unless it is a rectangle).

Solution. Let ABCD be an isosceles trapezium, where AD = BC and AB || CD. Draw perpendiculars AM and BN. Consider Δ ADM and Δ BNC. AD = BC. AM = BN (Perpendicular distance between two parallels is same) Therefore, from SAS congruency, we get: Hence, the base angles of an isosceles trapezium are equal. Suggest Corrections. 12.

In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram), and the diagonals have equal length. The base angles of an isosceles trapezoid are equal in measure (there are in fact two pairs of equal base angles, where one base angle is ...
Two base angles in an isosceles trapezoid are equal to one another. The angles of a trapezoid always add up to 360 degrees, just like any quadrilateral. Take a look at the following image to understand the isosceles trapezoid shape.

6 days ago · An isosceles trapezoid (called an isosceles trapezium by the British; Bronshtein and Semendyayev 1997, p. 174) is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. From the Pythagorean theorem, h=sqrt(c^2-1/4(b-a)^2), (1) so A = 1/2(a+b)h (2) = 1/2(a+b)sqrt(c^2-1/4(b-a)^2).
Base Angles. Diagonals. The defining trait of this special type of trapezoid is that the two non-parallel sides (XW and YZ below) are congruent.
