How many sides does an equilateral triangle
Web7 mrt. 2024 · From here we can first find the side length a and then we will use the perimeter formula to calculate the perimeter. For example, if we have an equilateral triangle whose height is 5cm. So we can get the side length a as, h = 3 2 a ⇒ 5 = 3 2 a ⇒ a = 5 × 2 3 = 7.07214 c m. Thus the perimeter is, P = 3 a = 3 × 7.07214 = 21.21641 c m. Webequilateral: [adjective] having all sides equal — see triangle illustration.

WebWhere a and b are two sides of a triangle, and c is the hypotenuse, the Pythagorean theorem can be written as: a 2 + b 2 = c 2 EX: Given a = 3, c = 5, find b: 3 2 + b 2 = 5 2 9 + b 2 = 25 b 2 = 16 => b = 4. Law of sines: the ratio of the length of a side of a triangle to the sine of its opposite angle is constant. Web31 jan. 2024 · A triangle can have 0, one, or two parallel sides. If a triangle has exactly one parallel side, then it is called an isoceles triangle. If a triangle has exactly two parallel sides, then it is called a equilateral triangle. An isoceles triangle has two congruent (equal) sides and angles.
WebProperties of a triangle. The properties of a triangle are: A triangle has three sides, three angles, and three vertices. The sum of all internal angles of a triangle is always equal to 180 °. This is called the angle sum property of a triangle. The sum of the length of any two sides of a triangle is greater than the length of the third side.
