Answer 2

Step-by-step explanation:

•Defination:-

An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length. . This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.

•Area: ½ × base × height

•Perimeter: 2 x (length of the two equal sides) + base of the isosceles triangle

•Number of vertices: 3

•Number of edges: 3

•Properties: Convex polygon, Cyclic

•Type: Triangle

•Line of symmetry: 1
