All angles have two sides!
An isosceles triangle has two sides and two angles that are the same.
A rectangle has two right angles and parcel sides
A right trapezoid can have no congruent sides and two right angles.
Yes as in the case of an isosceles triangle which has two equal sides and two equal base angles
A rhombus has two opposing acute angles (less than 90º) and two opposing obtuse (greater than 90º) angles, with the opposing sides being parallel and the sides being of equal length. A parallelogram can have the two acute angles and two obtuse angles, but have sides of different lengths. That is: two opposing sides shorter than the other two opposing sides. All angles total 360º
A parallelogram
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)

The base angles of an isosceles triangle that has two equal sides are equal.
Complementary.
They are equal.
