Adjacent angles are two angles that share a common vertex and a side but do not overlap. Congruent angles are angles that have the same measure, meaning they are equal in size. If two adjacent angles are congruent, they each measure the same, making them both equal in degree. This often occurs in situations involving geometric figures, such as when two angles form a straight line or a right angle.
square and a rectangle
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
yes but adjacent angles are not.
Congruent *apex
Sometimes they are, sometimes not.
Rhombus' Congruent AnglesIt's not the adjacent angles of a rhombus that are congruent, but the diagonal ones.
Rectangles have congruent adjacent angles.
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
A quadrilateral in which adjacent angles are congruent is called a kite. In a kite, the adjacent angles formed by the intersecting diagonals are congruent. This property distinguishes a kite from other types of quadrilaterals, such as a parallelogram or a rhombus, where adjacent angles are not necessarily congruent. Kites have specific properties and characteristics that make them a unique type of quadrilateral in geometry.

That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
