Use pythagoras' therom:
82-52 = 39 and the square root of this is 6.244997998
height = 6.245 ft to 3 d.p.
"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.

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
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.

Use Pythagoras' theorem: 82-52 = 39 and the square root of this is 6.244997998 or 6.245 feet in height to 3 d.p.
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.
A equilateral triangle and a normal triangle.
How about the shape of an isosceles triangle
An isosceles triangle can never be a scalene triangle but it can take the shape of a right angle triangle
A rhombus.
