The correct answer is Figure (C).
ABC is an equilateral triangle with sides of 24cm. Find the difference between its in-radius and circum-radius.
What is the area of an equilateral triangle with a side length of 8 cm?
If the ratio of the area of two similar triangles is √3:√2 then what is the ratio of the corresponding sides of the two triangles?
If each side of an equilateral triangle is 12 cm, then its altitude is equal to:
In a triangle ABC, the incenter is at O. Find angle BAC if angle BOC=120°.
If the inradius of a triangle with a perimeter of 60cm is 8 cm, then find the area of the triangle.(in cm2)
