Web18 mrt. 2024 · There are three vertices in a triangle. The maximum reflection of symmetry can be obtained are three. Reflection symmetry divides the side of the triangle into two equal parts. Hence, in equilateral triangle there are three lines of reflection symmetry. Kindly refer to the image attached to the answer. WebOne of the sides of an equilateral triangle is 22cm and the height is 16 cm what is the area • ( 1 vote) Ian Pulizzotto 6 years ago This is not a possible situation. It follows from the 30-60-90 right triangle side length ratio that the ratio of the height to the side length of an equilateral triangle is sqrt (3) / 2, or approximately 0.866.
How to find the length of one side of an equilateral triangle?
Web17 feb. 2016 · A. The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right. An isosceles triangle is a triangle with two congruent sides and one unique side and angle. Ex. An equilateral triangle is a triangle with three congruent sides and three congruent angles. Ex. 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. can bell\u0027s palsy cause sleep apnea
