If one side of an isoceles triangle has a measure of 12.1, then either... 1. One of the other sides is also 12.1. ...or... 2. The other two side as equal to each other but not equal to the known side. In both cases, the unknown side(s) are unknown, because the angles are not stated.
Depends from the given information. For example, if it is given the measure of the angle base θ, and the length of the base b, the sum of the sides a of the isosceles triangle equals to 2a = b/cos θ If it is given the measure of the angle base θ, and the length of the height h, the sum of the sides a of the isosceles triangle equals to 2a = 2h/sin θ If it is given the measure of the vertex angle θ, and the length of the base b, the sum of the sides a of the isosceles triangle equals to 2a = b/sin θ/2 If it is given the measure of the vertex angle θ, and the length of the height h, the sum of the sides a of the isosceles triangle equals to 2a = 2h/cos θ/2 If it is given the length measures of the base b and the height h, the sum of the sides a of the isosceles triangle equals to 2a = √(h4 + b2) (from the Pythagorean theorem)

No
A triangle that has 2 equal sides is an isosceles triangle
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.
An isosceles triangle has to have two sides of equal length. An isosceles triangle has to have two sides of equal length.
An isosceles triangle is a triangle that has at least 2 sides that are congruent.More simply put, an isosceles triangle has two sides of equal length (and therefore two equal angles opposite those equal sides)
An isosceles triangle has two equal sides.
An isosceles triangle has 3 sides and 2 of its sides are equal in lengths
The likely word is "isosceles" (triangle with two equals sides and angles).
