Question

How to find the area and perimeter of an isosceles triangle?

Explain with an example ​

Answer 1

Area :-

formula - A = 1/2×b×h

ex-

b - 12cm

h - 17cm

Area = (1/2)×b×h

= (1/2)×12×17

= 6×17

= 102cm

perimeter :-

formula - P = 2a+b?

ex-

a=5cm

b=9cm

Perimeter = 2a+b

=2(5)+9

= 10+9

= 19cm

Answer 2

Answer:

An isosceles triangle is defined as a triangle having two sides equal, which also means two equal angles. Here are some properties of an Isosceles triangle that distinguish it from other types of triangles:

The two equal sides of an isosceles triangle are called the legs and the angle between them is called the vertex angle or apex angle.

The side opposite the vertex angle is called the base and base angles are equal.

The perpendicular from the vertex angle bisects the base and it also bisects the vertex angle.
