Check the picture below.
so what are the lengths of the 1st and 3rd side anyway? well x - 4 and 2x.
1.) bass unit for mass is gram
2.) largest distance is kilometer
3.) smallest prefix is Milli
4.) centimeter because it measures length
5.) The standard unit that is used for each type of measurement
By Angle-Angle simlilarity postulate :
If two angles of one triangle congruent to two angles of another, then triangles must be similar.
So, I think the answer is
<span>All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
Because two base angles in </span>isosceles triangle are congruent, but it could be a lot of isosceles triangles that have different congruent base angles.
For example,
45-45-90 is an isosceles triangle, and 30-30-120 is an isosceles triangles, but they do not have 2 congruent angles.
