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.
legs of an isosceles 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.
If the vertex of an isosceles triangle has a measure of 70° what is the measure of one base angleANSWER:Isosceles = 2 legs, 1 vertex, 1 baseTriangle = 180°if its vertex measure 70° , 1 leg ____? + 1 leg____? =180° and all isosceles triangle has congruent legs.180°- 70°=110° then 110° divided by 2 =55°=vertex of an isosceles triangle measure 70° and its 2 legs measure 55°
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.
If two angle bisectors of a triangle are congruent, then the triangle is isosceles. This is because the angle bisectors of a triangle are concurrent and the angle bisectors of a triangle that are congruent divide the opposite sides of the triangle into two equal segments. So if two angle bisectors are congruent, the sides opposite those angles are also equal, making the triangle isosceles.
isos = equal, skelos = legs. A triangle with two equal legs is isosceles (not icsosceles!).
legs of an isosceles triangle
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
Actually, it is called an isosceles triangle. In Greek, isosceles means having equal legs: an isosceles triangles has two sides (legs) of equal length.
