Step-by-step explanation:
In figure, equilateral triangle all angles =60 degree.
Given, angle b=angle c
now, angle abp =180-60. [linear pair ]
=120degree
angle acq =180-60
=120 degree
hence, proved angle abp =angle acq
2.) perimeter of equilateral triangle is 210 cm
therefore, one side = 210/3
=70
now, area =1/2 × base × height
=1/2×70×70
=2450.
