First, you nee to know two things. One, you need to know the length of any one side (the base). Two, you need to know the height. The height is the length of a segment perpendicular to the base. if you know those two numbers, you can plug them into the following equation: A=1/2bh, where A is the area, b is the base, and h is the height.

What triangle is always similar?
An equilaterial triangle is always similar, because the corresponding angles are conqruent, it has the same basic shape, and it has a scale factor.
How many lines of symmetry has an equilaterial triangle?
There are three lines, three angles, and three sides or a triangle. Each angle of the equilateral triangle is exactly 60 degrees, because each angle is equal.
How do you find the area and perimiter of a triangle?
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
How do you find th area of triangle?
Area of a triangle = 0.5*base*perpendicular height
