Smart Math Formula Triangle, A triangle has three corners or vertices and three sides or edges which are straight line segments.

A Triangle has sides and the included angles of two triangles are correspondingly equal, the two triangles are congruent.

A Triangle has sides and the included angles of two triangles are correspondingly equal, the two triangles are congruent.

Area of Triangle. A = ½ . p . h

Perimeter of Triangle. P = a + b + c

Hypotenuse of Triangle. H²[bc²]= ab² + ac²

Note :

*p = pedestal , h = high , sides of triangle is a,b,c and Hypotenuse = H*

### Example

Question:

What is the area and perimeter of a triangle, if the triangle pedestal 4, height triangle 3,hypotenuse 5

Smart Math Answer :

Area of Triangle = ½ . p . h = ½ . 4 . 3 = 6

Perimeter of Triangle = a + b + c = 4 + 3 + 5 = 12

Question :

Right triangle pedestal [ab.4, height [ac)] 3. the length hypotenuse is

Smart Math Answer :

H² = ab² + ac²

H² = 4² + 3² = 16 + 9 = 25

H = √25 = 5
