Question

what is basic concepts of triangle

Answer 1

First of all,
These concepts should be known to deal with triangles,
1. Sum of all the angles of a triangle is 180°.
2. There are three types of triangle on basis of sides:
(a) Scalene triangle (All sides are unequal)
(b) Isosceles triangle (Two sides are equal)
(C) Equilateral triangle (All sides are equal)
2. There are three types of triangle on basis of angles:
(a) Acute (<90°)
(b) Right (=90°)
(C) Obtuse (>90°)
3. A triangle has three corners or vertices.
4. Sum of any two sides is always greater than the third side.

There are many... but these are main concepts.

Hope it helps !!!

Answer 2

1) The sum of all the angles of a triangle is 180*.
2) The sum of two sides of triangle is always greater than the 3rd side.
3)According to side triangle had 3 types
a) Isosceles triangle-two sides of a triangle are of equal length.
b) Equilateral triangle- the sum of all sides are equal
c) scalene triangle -the sum of all the sides are of different lenghts

4) According to angle triangle has three typs

a) Acute angled triangle - The triangle in which every angle is acute angle.

b) right angled triangle- the one angle of a triangle is right angle

c) obtuse angled triangle-the measure of one angle of a triangle is obtuse.
