Eisenmenger syndrome occurs when a congenital heart defect is not detected early enough to be treated before damage to the lung arteries occurs. If you or your child receives a diagnosis of a heart defect, it's important to start treatment promptly, including having surgeries or procedures to help correct the defect.
An acute angle is an angle with a measurement between 0Â° and 90Â°, or with less than 90Â° radians. It's the smallest of six different types of angles. There's an easy way to remember that an acute angle is small: think of it as a cute angle, perhaps visualizing a cute child playing an acute angle in a play about geometry.
Definition: An angle whose measure is less than 90Â°. Try this Adjust the angle below by dragging an orange dot and see how the angle â ABC behaves. Note that it is acute for all angles from zero to (but not including) 90Â°. Acute angles are the smallest, being between (but not including) zero and 90Â° Note also that acute triangles are those where all the interior angles are acute. A way to remember Sometimes we can confuse acute and obtuse angles. A way to remember is that small things tend to be cute. Acute angle is the smallest type. Types of angle
