Answer:
If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.
The fact which helps to prove the isosceles theorem is; The base angles of an equilateral triangle have equal measure.
Isoscelles triangle
Isoscelles triangles in plane shape concept are characterized by two equal sides.
On this note, similarly in equilateral triangles, 2 sides are equal ( although, all sides of an equilateral triangle are equal).
Ultimately, the statement which helps to prove the isosceles triangle theorem is therefore; The base angles of an equilateral triangle have equal measure since all the two sides are equal as in isoscelles triangles too.
