A triangle with angles that measure 30, 60, and 90 degrees is a special type of right triangle known as a 30-60-90 triangle. In this triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle. This relationship is based on the properties of trigonometry and the ratios of the sides in a 30-60-90 triangle.
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
the sum ofall 3 angles of a triangle is 180 degrees. If all of them are equal, then each is 60 degrees.
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
