These unique features make Virtual Nerd a viable alternative to private tutoring. An obtuse angle is an angle greater than 90° but less than 180°. Related pages. make an obtuse angle. It is an obtuse angle as it measures more than 90 degrees as shown: These sensor pairs were placed close to each other (6–7 mm) in order to measure the 200-mm wafer under nearly identical thermal conditions. One of the sides of this square coincides with a part of the longest side of the triangle. Think of it as a reclined car seat. An obtuse angle is a form of angle that measures wider than 90° and less than 180°. having an obtuse angle — see triangle illustration. In the given figure, ∠XYZ shows an obtuse angle. This is the most common type of truss in many areas, mostly due to its practicality. The longest side of an obtuse triangle is the one opposite the obtuse angle vertex.
Two angles that sum to one right angle (90°) are called complementary angles.

In an acute triangle, all angles are less than right angles—each one is less than 90 degrees. exceeding 90 degrees but less than 180 degrees. If one of the interior angles of the triangle is obtuse(i.e more than 90°), then the triangle is called the obtuse-angled triangle. An obtuse angle is a type of angle that is always larger than 90° but less than 180°. An obtuse angle is any angle larger than 90 degrees.
