Question

Types of triangles and finding area formulas and perimeter formulas

Answer 1

Triangles are categorised on the basis of side and angle:
on the basis of side-
* equilateral triangle having all sides equal.
* isosceles triangle with any two sides equal.
* scalar triangle having all unequal sides.
The perimeter of a triangle = sum of all sides
The area of a triangle = 1 by 2 × base × height

Answer 2

Hey mate......^_^

Here's ur ans. ⬇

➡ Types of triangles ⤵

✡ Scalene triangles --- Area = √s- (s-a) (s-b)(s-c). 【Heron's Formula 】

↪In scalene triangles all the sides have different magnitude.


✡ Isosceles triangle --- Area = 【Heron's Formula 】

↪In isosceles triangle two sides are equal .


✡Equilateral triangle --- Area = √3/4 side^2


↪In equilateral triangle all the sides are equal .



✡Right angle triangle ----- Area = 1/2 × base × height

↪In right angle triangle one angle is 90°.


◆ Perimeter of all kind of triangles is same I.e. "SUM OF ALL SIDES "

✨Hope it helps
