Construct the bisector of a given angle ABC.

The vertices of a triangle are A(3, 7), B(3, 4) and C(5, 4). The equation of the bisector of the angle /_ABC is

Show that the angle bisectors of a triangle are concurrent.

In a triangle ABC, CD is the bisector of the angle C. If cos (C/2) has the value 1/3 and 1(CD)=6, then (1/a+1/b) has the value equal to -

O is any point inside a triangle ABC. The bisector of angle AOB, angle BOC and angle COA meet the sides AB, BC and CA in point D, E and F respectively. Show that AD xx BE xx CF= DB xx EC xx FA

Construct a circumcircle of the triangle ABC where AB = 5cm, angleB = 75^@ and BC = 7cm

Draw the perpendicular bisector of a given line segment AB and write justification.

Objective : To construct a perpendicular bisector of a line segment using paper folding Procedure : Make a line segment on a paper by folding it and name it as PQ. Fold PQ in such a way that P falls on Q and thereby creating a creas RS. This line RS is the perpendicular bisector of PQ.
