No, not all angles are parallel.
That's a rectangle (possibly a square). If two sides are parallel, and all angles are right angles, then the other two sides must be parallel also.
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
A Hexagon has 3 pairs of parallel line and all angles are obtuse.
Angles cannot be parallel.
a rectangle or a square
Angles cannot be parallel.
Two different quadrilaterals have two pairs of parallel sides and have all their angles congruent. They are the square and the rectangle.
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)
A trapezoid (trapezium) has only 2 sides parallel and not all angles equal
The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.
It's a rectangle.
