That's an isosceles triangle.
It is an isosceles triangle when two of its three sides are of the same length.
All triangles have three sides. An isosceles triangle has two sides which are the same length and an equilateral triangle has all three sides of the same length.
A three-sided polygon is called a triangle. If two of the sides are of the same length, it is said to be an isosceles triangle.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
Triangles are congruent when:All three sides are the same length (SSS congruency)Two sides and the angle between them are the same length (SAS congruency)Two angles and the side between them are the same length (ASA congruency)
It is an isosceles triangle when two of its three sides are of the same length.
If only two sides of a triangle are the same length it is an isosceles triangle. If all three sides are the same length it is an equilateral triangle.

Only two of the three sides need to be the same size in an isosceles triangle.
There are two types of triangle: 1. Scalene triangle - no sides have the same length 2. Isosceles triangle - at least two sides have the same length a. Equilateral triangle - an isosceles triangle with 3 sides the same length.
that depends on the triangle. if the triangle has no two sides that are the same length, then it is called a scalene triangle and it has no lines of symmetry. if the triangle has two sides that are the same length, the triangle has one line of symmetry, starting at the angle where the two same length sides meet, and ending at the center of the opposite side. if all three sides are the same length, the triangle has three lines of symmetry, between any angle an the center of the opposite side.
rectangle
A three sided polygon in which two sides are equal in length and two angles are equal in size. Two sides have the same length as each other. The other side may be shorter or longer in length than the other two sides.
