Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
3 inches, an equilateral triangle has equal side lengths and angle measures
An Equilateral Triangle has equal side lengths and angle measures.
Each side measures 5 m
that is called an equilateral triangle. it has 3 angles that measure 60 degrees each.
Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
3 inches, an equilateral triangle has equal side lengths and angle measures
An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.
12 inches
An Equilateral Triangle has equal side lengths and angle measures.
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
Each side measures 5 m
that is called an equilateral triangle. it has 3 angles that measure 60 degrees each.
The perimeter of an equilateral triangle with a side length of 4 inches is 12 inches. Each side of an equilateral triangle is equal in length, so the perimeter is found by multiplying the side length (4 inches) by 3.
3*15 = 45 units.
39*3 = 117 units
The perimeter would be 18 cm.
