Which of the following conditions is correct for a right angled triangle?
1). Sum of the two angles of a triangle is greater than the third angle
2). Sum of the two angles of a triangle is less than the third angle
3). Sum of the two angles of a triangle is equal to the third angle
4). None of these
As, one angle of right angle triangle is 90° so by angle sum property sum of other two angles will be 90°
∴ Sum of two angles of a triangle is equal to the third angle
