It is an isosceles triangle
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.
No. It need not be the base angles that are equal, it can be one of the base angles and the top angle (if the triangle is tipped over). Also, the base angle are equal in an equilateral triangle - although an equilateral triangle is a special kind of isosceles triangle.
equal
An isosceles triangle is a triangle where two of its sides are equal, and hence two of its angles (often called "base angles") are equal. You can think of it as an equilateral triangle with one of its sides shortened or lengthened.
An isosceles triangle has two equal sides and two equal base angles.
An isosceles triangle has 2 equal sides and 2 equal base angles
An isosceles triangle has three interior angles whose base angles are equal.
The two base angles are equal
An isosceles triangle because its base angles are equal in size
Yes, the base angles of an isosceles triangle are always congruent. An isosceles triangle commonly has two sides that are equal in length. The base angles are the angles opposite those two equal sides of the triangle. A geometric theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. The converse is also true.
The two angles have the same measure; they are equal. An iscosceles triangle has two equal sides. It also has two equal angles, and each of these angles will be opposite one of the equal sides. The two angles will also each contain the base. The two angles must be equal.
Yes! An isosceles triangle has 2 equal sides and two base angles equal.
