An acute angle is an angle of a shape under 90 degrees, an angle over 90 degrees is called an obtuse angle. hope this helps!:D
A Right Isosceles Triangle is a shape that has one 90° angle. 90 degrees + the other two angles add up to 180 degrees.
It is a right angle
The angle measures 90 degrees.
A right angle triangle.
A square, A rectangle
L shape
right, cheesy swept!
A right angle triangle must have a 90 degree angle and two acute angles.
If the angle is over 90 degrees the angle is obtuse, smaller than 90 degrees the angle is acute and over 180 degress the angle is a reflex angle
A 90 degree angle is also known as right angle. A right angle (or 90 degrees) looks like an L shape. A square or rectangle's four corners are all 90 degrees.
well, if your asking if and acute shape is a wide leaned back angle, well then the answer is no. that's and obtuse angle. and acute angle is smaller than 90 degrees and an obtuse angle is larger than 90 degrees.
