Answer» D)Isosceles triangle Given: △ABC, AP BISECTS BC and AP⊥BC Now, In △APB and △APC ∠APB=∠APC (Each 90∘) AP=AP (Common) PB=PC (AP bisects BC) Thus, △APB≅△APC (SAS Rule) Hence, AB=AC (By cpct) Thus, △ABC is an ISOSCELES TRIANGLE.

Answer»

D)Isosceles triangle

Given: △ABC,

AP BISECTS BC and AP⊥BC

Now, In △APB and △APC

∠APB=∠APC (Each 90∘)

AP=AP (Common)

PB=PC (AP bisects BC) Thus, △APB≅△APC (SAS Rule) Hence, AB=AC (By cpct)

Thus, △ABC is an ISOSCELES TRIANGLE.
