Angles and sides are congruent when they are identical. A shape with four identical sides and angles is a square.
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
a regular polygon
This is a rectangle.
A rectangle has 4 congruent angles. 90 degrees. It is also a parallelogram, 2 pairs of congruent sides.
A shape with 4 right angles and 4 equal sides is a square. ==========================
no because if an scalene triangle had 2 congruent angles it wouldn't be a scalene it would be a isosceles triangle because an isosceles triangle is the only triangle with 2 congruent angles
Rhombus. Because a rhombus has congruent (egual in shape and size) sides, but has no right angles.
rectangle
yes because a square is, by definition, a shape having 4 ninety degree angles, and four congruent sides
It would be if all its sides and all its angles were congruent. Otherwise, not.
