Answer:
In a triangle, the perpendicular from vertex to the base bisects the base. The triangle is Isosceles.
Step-by-step explanation:
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.
