Question

Find five situations where obtuse angles are made.

Answer 1

Hint: Try observing obtuse angles that we experience in daily life activities.

Complete step-by-step answer:

We have to write the five situations where obtuse angles are made.
Before writing those we will first briefly learn what is an angle and what is an obtuse angle.
In plane geometry, an angle is formed by two rays, called the sides of a triangle sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces. These are called dihedral angles. Angles formed by the intersection of two curves in a plane are defined as the angles determined by the tangent rays at the point of intersection.
Angles is used to designate the measure of an angle or of a rotation. This measure is the ratio of the length of a circular arc to its radius. In case of geometric angle, the arc is centred at the vertex and delimited by the sides. In case of rotation, the arc is centred at the centre of the rotation and delimited by any other point and its image by the rotation.
One of the types of angles is an obtuse angle.
An obtuse angle is an angle of greater then $90{}^\circ $ and less then $180{}^\circ $. It is smaller than a straight line angle which measures $180{}^\circ $.
Also, we can see obtuse angles in real life situation too for example:
(i)The open book for reading.
(ii)Wide open cupboard door.
(iii)Rooftop
(iv)Clock showing 8 o'clock.
(v)Base of tripod stand.
  The open book for reading, Wide open cupboard door, Clock showing 8o'clock, Base of tripod stand.

Note: There are many other examples too like car windshields, umbrellas, also the border between the state of Nevada and state of California, near Reno.
