An isosceles triangle has three interior angles whose base angles are equal.
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.

Triangle
The only requirement for an isosceles triangle is that two sides be the same length and one be different. It is possible for an isosceles triangle to have two perpendicular legs. It would be right and isosceles.
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
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 base angles of an isosceles triangle are the two angles with the same measure, each formed by the intersection between the base of the triangle and one of the two legs.
The congruent sides of an isosceles triangle are the two sides that are equal in length. These two sides are opposite the equal angles of the triangle. The third side, called the base, is not equal in length to the other two sides.
Equal angles and equal lengths
An isosceles triangle has at least two equal sides and two equal angles An isosceles triangle has two or more congruent sides called legs. In an isosceles triangle with just two congruent sides, the angle formed by the legs is called the apex, and the other two angles, called base angles, are congruent. If the isosceles triangle has three congruent sides (AKA an equilateral triangle), then all three sides and angles are congruent, and there are no definitive base or vertex angles, besides...all of them.

An isosceles triangle is a triangle with two equal sides and two equal angles. The two equal sides are called the legs, and the angle between them is called the vertex angle. The two other angles in an isosceles triangle are equal and are called the base angles.
isos = equal, skelos = legs. A triangle with two equal legs is isosceles (not icsosceles!).
legs of an isosceles triangle
The two angle bisectors of a triangle are congruent the those two angles are congruent. The angles are bisected the same meaning that the whole and half angle are the same. For example if they are bisected at the whole angle 50 each, then each half is 25. The bisectors really don't mean anything and all you need is 50 to know it's isosceles. 50 and 50 is 100 and the left over for the last angle is 80 adding to 180. AND overall any 2 congruent angles in a triangle have the same congruent legs making it isosceles.
Yes, isosceles triangles can be right triangles. An isosceles triangle has at least two sides of equal length, and if one of the angles is a right angle (90 degrees), the triangle is classified as a right isosceles triangle. In this case, the two equal sides are the legs of the triangle, and the third side is the hypotenuse.
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
