You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
that side of the triangle is only 7 inches long
Only an equilateral triangle are all sides congruent
A isosceles triangle has only two sides the same length unlike other types of triangle which either have one or none. If your wondering what triangle has only one side equal it is the isosceles also, (think about it,)
Two sides of an isosceles triangle are equal. The base is the other side.
A triangle by definition only has 3 sides, so a 5-sided triangle does not exist - unless you are including the in-side and out-side of it as two more sides. A five sided polygon is a pentagon.

You can't. You need 2 sides.

An isosceles triangle has two congruent sides.
if the triangle was an equilateral triangle, you would have been able to just multiply 45 with 3... but if the triangle was some other kind of triangle, you would have to know the other sides

A triangle with 3 equal sides is an equilateral triangle. A triangle with 2 equal sides is an isosceles triangle. There is no such thing as a triangle with ONE equal side. Equal to what? If you wish to stretch it and say each side is (equal to itself only ) not equal to any others it is a scalene triangle.
Spheres, eggs, footballs, oblate and prolate spheroids, as well as most other finite solids of revolution, each have only two sides ... the in-side and the out-side.
An isosceles triangle has two sides of equal length.
The perimeter of any triangle is the sum of its 3 sides.
