90 degrees
A right angle triangle.
A triangle with a right angle is a right triangle.
Any triangle that has a 90 degree angle and two acute angles is a right angle triangle.
Any triangle with a 90 degree angle is classified as a right triangle.
They are classified as: scalene, obtuse, right angle. equilateral and isosceles
Triangles can be classed as scalene, right angle, obtuse, isosceles and equilateral
If the measure of angle A is 90 degrees, then it is classified as a right angle. Right angles are characterized by their exact measurement of 90 degrees, and they are commonly found in various geometric shapes, such as squares and rectangles.
No. An obtuse angle is greater than 90o and less than 180o. A 180o angle is classified as a straight angle.
When the sum of two angles is 90 degrees, the angles are classified as complementary angles. This means that each angle, when added to the other, results in a right angle. For example, a 30-degree angle and a 60-degree angle are complementary because their sum is 90 degrees.
No. An acute triangle has to have three acute angles. A right triangle has to have one 90 degree angle.
A 70 degree angle is classified as acute because it is less than 90 degrees.
A 68-degree angle is classified as an acute angle, as acute angles are defined as being less than 90 degrees. This means it is sharper than a right angle but not as sharp as an angle that is less than 0 degrees.
