Bisectors of angle B and angle C of a triangle ABC intersect each other at point O.Prove that angle BOC=90degree+half of angle A.
m and n are plane mirrors perpendicular to each other. Prove that incident ray CA (to mirror n ) is parallel to reflected ray (to mirror m ) BD.
Respected Sirs,
Please answer my this question as soon as possible. I tried to insert the figure from ms-paint file but was unable to do so. But I believe that the question is self descriptive.
"Angle Q is greater than angle R and M is a point on QR such that PM is the bisector of angle QPR If the perpendicular from P on QR meets at N, prove that angle MPN =1/2(angle Q-angle R)
Can you explain me the angle sum property of a triangle ?
if two straight lines intersect each other prove that the ray opposite to the bisector of one of the angles thus formed bisects the vertically opposite angles
plz answer this immediately , its most urgent
in a right angeled triangle , one acute angle is double the other. proove that the hypotenuse is double the smallest side?
If the arms of one angle are respectively parallel to the arms of another angle, show that the two angles are either equal or supplementary.
Find the measure of an angle, if seven times its complement is 10 less
that BAL = ACB.
parallel to each other.
The sides BC, CA and AB of Triangle ABC, are produced in order, forming exterior angles /_ACD, /_BAE and /_CBF. Show that
angle ACD + angle BAE + angle CBF = 360 degree.
If two parallel lines are cut by a transversal ,prove that the bisectors of the interior angles on the same side of the tranversal intersect each other at right angles
