prove that the angles opposite to equal sides of an isosceles triangle are equal. Using the above, find <b in with AB=BC in which <c=50.
Prove that the bisectors of pair of Vertically opposite angles are on the same straight line..
(please i want the answer by the expert..)
if two parallel lines are intersected by a transversal,then prove that bisectors of the interior angles form a rectangle.
Prove that if the two arms of an angle are perpendicular to the two arms of another angle, then the angles are either equal or supplementary.
if two parallel lines are intersected by a transversal prove tha bisectors of the two pair of interior angles enclose an rectangle
plz answer it immediately its most urgent
in the figure, the side BC of triangle ABC is produced to D. the bisector of angle A meets BC at L. prove that angle ABC+ angleACD= 2 angle ALC
An angle is 20degrees more than three times the given angle . If the two angles are supplementary , the angles are :
a. 20 degrees , 160 degrees
b. 40 degrees , 140 degrees
c. 60 degrees , 120 degrees
d. 70 degrees , 110 degrees
A transversal intersects two parallel lines. Prove that the bisectors of any pair of corresponding angles so formed are parallel.
Please send the answer as soon as possible
Triangle ABC is an isosceles triangle with AB=AC, side BA is produced to D such that AB=AD. Prove that angle BCD is a right angle.
bisector of angle b and angle d of a quadrilateral abcd meet cd and ab produced at point p and q respectively prove( angle p +angle q=1/2 angle abc +angle adc)
