If three angles of one triangle are congruent to three angles of another triangle then by the AAA similarity theorem, the two triangles are similar. Actually, you need only two angles of one triangle being congruent to two angle of the second triangle.
You use Lami's theorem wen you triangle of forces to calculate the sides of the triangle or the angles opposite to a side.
The sum of all inner angles within a triangle is 180 degrees.
That is called an equilateral triangle. An equilateral (equal sides) triangle is also equiangular (equal angles), so it follows that all angles are 60 degrees.That is called an equilateral triangle.

The sum of the interior angles of a triangle in euclidean geometry equal 180 degrees
The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
The theorem that states every triangle's angles add up to 180 degrees
The AA similarity theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This theorem is based on the Angle-Angle (AA) postulate, which states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
The sum of all inner angles within a triangle is 180 degrees.
The Isosceles Triangle Theorem:If two sides of a triangle are congruent, then the angles opposite the sides are congruent.The Converse of Isosceles Triangle Theorem:If two angles of a triangle are congruent, then the sides opposite those angles are congruent.
The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.

Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
Yes an isosceles triangle has two equal sides and two equal angles.
