Suppose we are trying to draw triangle ABC so that the measure of angle ABC is 30, the length of segment BC is 20 units, and the length of segment AC is among the lengths 9.5 units, 10 units, 15 units, 20 units, and 25 units. For how many of these choices for the length of will we be able to draw two non-congruent triangles satisfying the ... WebIn an isosceles triangle ABC, with AB = AC, the bisectors of ∠B and ∠C intersect each other at O. Join A to O. Show that: (i) OB = OC (ii) AO bisects ∠A Solution (i) It is given that in triangle ABC, AB = AC ⇒ ∠ACB = ∠ABC (Angles opposite to equal sides of a triangle are equal) ⇒ ∠ACB = ∠ABC ⇒ ∠OCB = ∠OBC lithium wt gain
