ABC is an equilateral triangle with side length equal to 50 cm. BH is perpendicular to AC. MN is parallel to AC. Find the area of triangle BMN if the length of MN is equal to 12 cm.

None but all three sides are equal in length.
The altitude of an equilateral triangle is (√3)/2*a. where 'a' is the side of the triangle. It can be just find by giving a perpendicular to the base of the triangle, the base of the triangle become a/2 and one side is a. so by applying Pythagoras theorem we will get the desired formula.
is called an equilateral triangle
none, the three sides meet so there are no parallel sides but all the sides are equal.
An equilateral triangle
a equilateral triangle has all the sides the same length.
All three sides of an equilateral triangle are..."equal" in length.
An isoceles triangle has TWO sides of equal length but an equilateral triangle has THREE sides of equal length
All three sides are equal in length.
An equilateral triangle is one whose three sides are the same length.
