if any two angles are similar the triangle will be similar
An equilateral triangle is a triangle with three equal sides. An isosceles triangle is one with two equal sides. So yes, an equilateral triangle qualifies as being an isosceles triangle as well. This is quite similar to the relationship between squares and rectangles, where a square is always a rectangle, but a rectangle isn't necessarily a square.

A right angle triangle with 45, 45 and 90 degree angles is similar to an isosceles triangle
No.

Peers are people of similar age who share similar interests. While a casual friendship is a relationship between peers who share something in common. :D

The ear and kidney have a similar shape
They must be the same.
why triangle are similar
If you double (2 times) the perimeter the area will will be 4 times larger. Therefore the area is proportional to the square of the perimeter or the perimeter is proportional to the square root of area. The relationship as shown above applies only to triangles with similar proportions, that is when you scale up or down any triangle of fixed proportions. Other than that requirement, there is no relationship between perimeter and area of any shape of triangle except that it can be stated that the area will be maximum when the sides are of equal length (sides = 1/3 of perimeter).
