To determine the measure of angle ( DAB ) in an isosceles trapezoid, you need to know the measures of the other angles or the lengths of the bases. In an isosceles trapezoid, the base angles are equal, so if you have the measure of one base angle, angle ( DAB ) will be the same. If additional information about the trapezoid is provided, please share it to get a more precise answer.
False.
parallel
An isosceles trapezoid is a quadrilateral that has parallel bases of different lengths, two equal sides and the lateral base angles are equal. Interior angles add up to 360 degrees Exterior angles add up to 360 degrees
An isosceles trapezoid has 1 vertical line of symmetry
In an isosceles trapezoid, the opposite angles are equal. Specifically, the angles adjacent to each of the bases are congruent; that is, the angles on the same side of the trapezoid are equal to each other. Therefore, if one angle measures ( A ), the angle directly opposite it will also measure ( A ), while the other two angles will also be equal, forming a pair of equal angles on each base.
No, an isosceles trapezoid does not have four congruent sides. An isosceles trapezoid has a pair of parallel sides (the bases) and the non-parallel sides (the legs) are of equal length, but the lengths of the bases are generally different. Thus, it has only two pairs of congruent sides, not four.
No. The other two sides are congruent.
No, it is not.
C. Congruent Bases
No its parallel bases can never be equal in length. But if it is in the form of an isosceles trapezoid then its slanted sides are equal in length.
