Construct the bisector of a given angle ABC.

Name the instruments needed to construct the perpendicular bisector of a given line segment.

In trianle ABC, CD is the bisector of the angle C. if cos . C/2 = 1/3 and CD = 6, then the value of (1/a + 1/b) = 1/lambda , " then " lambda is

If the bisector angle A of the triangle ABC makes an angle theta with BC, then sin theta=

Construct a perpendicular bisector of line segment overline (AB) = 4.2cm.

draw the angular bisector of right angle ?

ABC is a triangle with angle B greater than angle C . D and E are points on BC such that AD is perpendicular to BC and AE is the bisector of angle A. Complete the relation angle DAE = 1/2 [(…..) - angle C]

A (1,3) and C (-2/5,-2/5) are the vertices of a triangle ABC and the equation of the angle bisector of angleABC is x+y =2 Equation of side AB is

In the adjacent figure, ABC is a triangle in which angleB = 50^(@) and angleC = 70^(@) . Sides AB and AC are produced. If ‘z’ is the measure of the angle between the bisectors of the exterior angles so formed, then find 'z'.

When we construct a triangle similar to a given triangle as per given scale factor, we construct on the basis of ………
