It is an acute angle. All angles from 1 - 89 degrees are acute. A 90 degree angle is a right angle. Angles from 91 - 179 are obtuse angles.
They have one 90 degree angle and two 45 degree angles
The right angle = 90 degree. If x is an angle and if these 3 angles are equal then x + x + x = 90 3x = 90 x = 90/3 x = 30 degree So, the angle is 30 degree each.
If it has a 90 degree angle and two acute angles then it is a right angle triangle.
4 right angles. A right angle is a 90 Degree measure like for example: L <---- 90 degree measure. And the rectangle has 4 angles like that so it means it has 4 right angles.
An acute triangle.
No A right angle has 90 degree A triangle has 180 degreeYes, a right triangle has one right angle and two acute angles. The sum of the acute angles is 90°.
180 Degree.
A right angle.
a right angle is exactly a 90 degree angle. for example, there are 4 right angles on a square, the corners are right angles. like the edges on papers that is a right angle. an oblique line is smaller than a right angle.
angles exactly at a 90 degree angle like an L
Straight angle, which is 180 degree, obtuse angle, which is 179 degree to 91 degree, right angle, which is 90 degree, and acute angle, which is 89 degree to 1 degree.
