Scalene triangle
if the angles of a figure are the same but the sides aren't, it is similiar. Congruent is angles and sides exactly the same
A similar figure has the same interior angles as a congruent figure but its sides are in proportion to a congruent figure.
Yes, they are.
marks used on a figure to indicate congruent
None! If the angles are not congruent then the shapes are not similar of congruent. But that is not a problem. The angles of an equilateral triangle are not congruent to the angles of a square but that does not mean that you cannot work with equilateral triangles or squares!
A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
A quadrilateral with 4 right angles cannot have just two congruent sides so, unless this is a trick question (2 congruent sides does not excluded the possibility of more than 2 congruent sides), the answer is there is no such plane figure.
It is a regular polygon
A square.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
If only two sides of one figure are congruent to two sides of another figure, you can say nothing about the opposite angles.
No, you cannot.
