Not sure about angels, but if angles will satisfy you, the answer is a rectangle
A General Quadrilateral
It can also be a kite. That has two congruent pairs of sides but unlike a parallelogram they are adjacent, not opposite. A parallelogram with congruent diagonals is a rectangle.
A kite has two pairs of adjacent sides congruent. The diagonals intersect at right angles and bisect one set of angles.
A rectangle is the only such shape. Not sure about the "little" right angles: all right angles are of the same measure.
A square:) :) :)
It is a rhombus. If the sides form right angels, it can also be classified as a square. It is a rhombus. If the sides form right angels, it can also be classified as a square. It's a rhombus.
A rectangle.
A parallelogram
Parallelogram
A rectangle has two pairs of congruent sides, but any pair of adjacent sides is non-congruent.
This is a rectangle.
