ANGLES The three angles `\_ BAC \_ ABC and \_ACB` are called the angles of `DeltaABC`.

ANGLES The three angles -BAC-ABC and -ACB are called the angles of Delta ABC .

Find all the three angles of the DeltaABC .

In DeltaABC , the point at which the bisectors of the angles /_ABC and /_BAC intersect is called the incentre of the triangle.

angleBAC : angle ABC : angle ACB = what ?

In the figure given, angle BAC : angle ABC = 2:3. Find the measure of angleABC .

In a DeltaABC , angleA+ angle B=125^(@) and angle B+ angle C=150^@ . Find all the angle of Delta ABC.

Exterior angle ACD= 135^@ and /_ABC and /_BAC are in the ratio 3:2 Find all the angles of the triangles

Delta ABC is inscirbed in a circle, the bisector of the angles angle BAC, angle ABC and angle ACB intersect at the point X,Y,Zon the circle repectively. Prove that in Delta XYZ , angle YXZ=90^(@)-(1)/(2) angle BAC

The triangle ABCis inscribed in a circle, AX, BY and CZ of the angles angle BAC, angle ABC and angle ACB , intersect at the point X,Y,Z on the circle respectively. Prove that AX is perpendicular to XZ.

In ABC, if /_B=60^(@),/_C=80^(@) and the bisectors of angles /_ABC and /_ACB meet at a point O, then find the measure of /_BOC .
