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.
An acute triangle is a triangle with all three angles acute (less than 90Â°). An obtuse triangle is one with one obtuse angle (greater than 90Â°) and two acute angles.Since a triangle's angles must sum to 180Â°, no triangle can have more than one obtuse angle.n obtuse triangle is one with one obtuse angle (greater than 90Â°) and two acute angles.
