Rocky Mountain National Park Visits Could Cost More. DENVER (CBS4) â Each year more than 3 million people visit Rocky Mountain National Park but it may soon cost more to get in. For the first time in 9 years thereâs a proposal to have park visitors pay $20 for a 1-day pass or $30 for a 7-day pass.
In an equiangular triangle, all the angles are equalâeach one measures 60 degrees. An equiangular triangle is a kind of acute triangle, and is always equilateral. In a right triangle, one of the angles is a right angleâan angle of 90 degrees. A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angleâit is more than 90 degrees. An obtuse triangle may be isosceles or scalene. In an acute triangle, all angles are less than right anglesâeach one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.
A triangle must be either acute, right, or obtuse. It also has three interior angles that always total 180 degrees. Because a right triangle has a right angle (exactly 90 degrees), the sum of its two remaining angles must be 90 degrees. These two angles are therefore inferred to be acute. The same holds true for an obtuse triangle, since it has an obtuse angle (measuring more than 90 degrees) that makes the sum of its two other angles be less than 90 degrees. No triangle has only one acute angle, or it wouldn't be a triangle.
