"Congruent" means "same shape and size as the other one". So one thing all by itself is never congruent. It needs something else to be congruent with. An isosceles triangle is never congruent to a scalene triangle, sometimes congruent to any other kind of triangle, and always congruent to another isosceles triangle that's congruent to the first one.

No. Two shapes are congruent if they have the same size and shape. The area of a triangle is found with the formula 1/2 x base x height. Example: Triangle A has a base of 2 and a height of 4, so its area is 4 square units. Triangle B has a base of 1 and a height of 8, so its area is also 4 square units, but it is a different shape.

An isosceles triangle is a triangle (3-sided, 2-dimensional shape), 2 sides of which are equal in length. Any triangle which is not equalateral

An isosceles, possibly equilateral, triangle

In a general trapezium, the non-parallel sides are not congruent. However, in an isosceles trapezium, the non-parallel sides are congruent. So the shape is like an isosceles triangle with its apex chopped off by a straight line parallel to its base.
