draw a triangle & its exterior angle on one side and name he exterior angle as4 and interior opp. angle as 1 and 2 and name the third angle as 3 now we know exterior angle is equal to the sum of interior opp. angle so,angle1+angle2=angle 4 we also know angle3+angle4=180(linear pair) NOW from this 2 equation angle1+angle2+angle3=180
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
because INTERIOR ANGLE 180 AND the exterior angle 180 so 180+180=360
Angle a plus angle b subtract from 180 equals angle c
first we draw a triangle than we mark3angle of triangle. now think that which no. comes in all 3 angle of triangle that equals to 180 degrees because the sum of 3angles are 180 degr ees.
The three angle sum of ANY triangle is 180 degrees.
The sum of the three interior angles of a triangle is always 180 degree is known as angle sum property of a triangle.

Euclid and Pythagoras.
This is not possible. If a triangle is a Right angled triangle then the sum of the two angles which are not right will be = 90 [Angle Sum Property] That's why you see.
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
Irrespective of the size or shape of the triangle, its angles total 180o.
because INTERIOR ANGLE 180 AND the exterior angle 180 so 180+180=360
Angle a plus angle b subtract from 180 equals angle c
For any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
first we draw a triangle than we mark3angle of triangle. now think that which no. comes in all 3 angle of triangle that equals to 180 degrees because the sum of 3angles are 180 degr ees.
The three angle sum of ANY triangle is 180 degrees.
