14.	1. If each angle of a triangle is less than the sum of the other two, show that the triangle is acute angle.
Answer» Let, ABC is a triangle. Then, ANGLE A+angleB+angleC=180°---------------(1) If angle A + angle B < angle C Then, using equation (1), we GET, angle C + angle C < 180° => 2 angle C < 180° => angle C < 180°/2 => angle C < 90° Similarly , we get, angle A < 90° and angle B < 90° If each angle of a triangle is less than 90°,it is KNOWN as acute triangle. Hence,ABC is a acute triangle. SHOWED.

Discussion

15.	1. If one angle of a triangle is equal to the sum of the other two, show the triangle is a right triangle.
Answer» Let ABC is a triangle,in which ANGLE B is equal to the sum of angle A and angle C. So,In triangle ABC, angle B = angle A+angle C -------------------->(1) Now, we know that, angle A+ angle B+ angle C = 180° =>angle B+(angle A+angle C) = 180° => angle B+angle B = 180° [From (1)] => 2 angle B = 180° => angle B = 180°/2 => angle B = 90° If ONE angle of a triangle is90°,the triangle is KNOWN as right triangle. So,ABC is a right triangle. Proved.
