The definition of an obtuse angle in geometry states that an angle larger than 90° but less than 180° is called an obtuse angle. We can use a protractor and mark any angle between 90° and 180° to draw an obtuse angle.

An obtuse angle is an angle with angle measure greater than 90° and less than 180°. In other words, it lies between 90° and 180°. So, what does an obtuse angle look like? How many degrees does an obtuse angle measure? Take a look at the given Obtuse Angle diagram to understand its range better.
To extend our definition of the trigonometric ratios to obtuse angles, we use a Cartesian coordinate system. We put an angle θ in standard position as follows: Place the vertex at the origin with the initial side on the positive x x. -axis; the terminal side opens in the counterclockwise direction. We choose a point P P.
An angle is an amount of rotation. It is measured in degrees. Angle language: Labelling angles: or Also: . angle. arm vertex. We refer to the reflex angle as ‘reflex ,′. Exercise 1: (a) In the diagram below name: 5 acute angles. 2 right angles. 10 pairs of adjacent angles. 3 obtuse angles. 1 2.
Answer. Activity 3.1 Obtuse Angles. An obtuse angle has measure between \ (90^ {\circ}\) and \ (180^ {\circ}\). In this section we will define the trigonometric ratios of an obtuse angle as follows.
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. For better understanding, look at the following example.
Obtuse angle Definition: An angle whose measure is greater than 90° and less than 180° Try this Adjust the angle below by dragging the orange dot at A and see how the angle ∠ ABC behaves.
