In `Delta` ABC, m `angle` A = m `angle` B = `90^@`, m `angle` C = `45^@`. Is this triangle possible ? Why?

If in a Delta ABC, angle A = 45^(@) , angle B = 75^(@), then

Name the types of triangles formed in two different ways in each of the following : (i) A triangle in which one angle is of 90^(@) , and the other two angles are equal. (ii) A Delta ABC with m angle A = 40^(@), m angle B = 60^(@) and m angle C = 80^(@) . (iii) A triangle in which one angle is obtuse and the other two angles are equal.

In Delta ABC , angle A + angle B= 65^@ , angle B + angle C = 140^@ then find angle B .

In a Delta ABC , angle A + angle B = 118^@ angle A + angle C = 96^@ . Find the value of angle A

In a Delta ABC angle C = 60^(@) angle B = 90^(@) find the ratio of sides

In a Delta ABC angle A + angle B = 145^(@), 2 angle B + angle C = 180^(@) Find angle A and angle B

In a Delta ABC, angle C = 3 angle B = 2 (angle A + angle B) , then angle B = ?

If in a Delta ABC, b =sqrt3, c=1 and B-C =90^(@), then angle A is

In triangle ABC , AB = AC , angle B = 40 ^(@) Then angle C is equal to
